For those who are still getting blank response with $request->getContent(), you can use:

$request->all()

e.g:

public function foo(Request $request){
   $bodyContent = $request->all();
}

I created a module that works equal to the official Broadcastchannel but has fallbacks based on localstorage, indexeddb and unix-sockets. This makes sure it always works even with Webworkers or NodeJS. See pubkey:BroadcastChannel

mine was:

<youtube-player
  [videoId]="'paxSz8UblDs'"
  [playerVars]="playerVars"
  [width]="291"
  [height]="194">
</youtube-player>

I just removed the line with playerVars, and it worked without errors on console.

Another reason this could be happening is if you are using an iframe that has the sandbox attribute and allow-same-origin isn't set e.g.:

// page.html
<iframe id="f" src="http://localhost:8000/iframe.html" sandbox="allow-scripts"></iframe>
<script type="text/javascript">
    var f = document.getElementById("f").contentWindow;
    // will throw exception
    f.postMessage("hello world!", 'http://localhost:8000');
</script>

// iframe.html
<script type="text/javascript">
    window.addEventListener("message", function(event) {
        console.log(event);
    }, false);
</script>

I haven't found a solution other than:

• add allow-same-origin to the sandbox (didn't want to do that)
• use f.postMessage("hello world!", '*');

UPDATE 2018 MAY:

Alternatively, you can embed Edge browser, but only targetting windows 10.

Here is the solution.

Getting a cross-domain JSON with jQuery in Internet Explorer 8 and newer versions

Very useful link:

http://graphicmaniacs.com/note/getting-a-cross-domain-json-with-jquery-in-internet-explorer-8-and-later/

Can help with the trouble of returning json from a X Domain Request.

Hope this helps somebody.

I resolve this problem on NodeJS like this:

var util = require('util');

// Our circular object
var obj = {foo: {bar: null}, a:{a:{a:{a:{a:{a:{a:{hi: 'Yo!'}}}}}}}};
obj.foo.bar = obj;

// Generate almost valid JS object definition code (typeof string)
var str = util.inspect(b, {depth: null});

// Fix code to the valid state (in this example it is not required, but my object was huge and complex, and I needed this for my case)
str = str
    .replace(/<Buffer[ \w\.]+>/ig, '"buffer"')
    .replace(/\[Function]/ig, 'function(){}')
    .replace(/\[Circular]/ig, '"Circular"')
    .replace(/\{ \[Function: ([\w]+)]/ig, '{ $1: function $1 () {},')
    .replace(/\[Function: ([\w]+)]/ig, 'function $1(){}')
    .replace(/(\w+): ([\w :]+GMT\+[\w \(\)]+),/ig, '$1: new Date("$2"),')
    .replace(/(\S+): ,/ig, '$1: null,');

// Create function to eval stringifyed code
var foo = new Function('return ' + str + ';');

// And have fun
console.log(JSON.stringify(foo(), null, 4));

Probably you try to send your data from mydomain.com to www.mydomain.com or reverse, NOTE you missed "www". http://mydomain.com and http://www.mydomain.com are different domains to javascript.

Might help some else - I came here because I missed putting two // after http:. This is what I had:

http:/abc.my.domain.com:55555/update

In spring servlet .xml :

<context:component-scan base-package="net.controller" />

(I assumed that the service impl is in the same package as the service interface "net.service")

I think you have to add the package net.service (or all of net) to the component scan. Currently spring only searches in net.controller for components and as your service impl is in net.service, it will not be instantiated by spring.

Well... its quite simple to get a SQL min date

DateTime sqlMinDateAsNetDateTime = System.Data.SqlTypes.SqlDateTime.MinValue.Value;

An enum is kind of like a typedef for the int type (kind of).

So the type you've defined there has 12 possible values, however a single variable only ever has one of those values.

Think of it this way, when you define an enum you're basically defining another way to assign an int value.

In the example you've provided, january is another way of saying 0, feb is another way of saying 1, etc until december is another way of saying 11.

I've found using an additional class on the .panel-heading helps.

<div class="panel-heading contains-buttons">
   <h3 class="panel-title">Panel Title</h3>
   <a class="btn btn-sm btn-success pull-right" href="something.html"><i class="fa fa-plus"></i> Create</a>
</div>

And then using this less code:

.panel-heading.contains-buttons {
    .clearfix;
    .panel-title {
        .pull-left;
        padding-top:5px;
    }
    .btn {
        .pull-right;
    }
}

I disagree on the comment posted by Hogan. Those instructions will work for IBM DB2 Mini, but it's not the case of DB2 Z/OS.

Here is an example:

Exception data: org.apache.ibatis.exceptions.PersistenceException:
The error occurred while setting parameters

SQL: INSERT INTO TABLENAME(ID_, F1_, F2_, F3_, F4_, F5_) VALUES
 (?,          1,          ?,          ?,          ?,          ?),          
 (?,          1,          ?,          ?,          ?,          ?)


Cause: com.ibm.db2.jcc.am.SqlSyntaxErrorException: 
ILLEGAL SYMBOL ",". SOME SYMBOLS THAT MIGHT BE LEGAL ARE: FOR <END-OF-STATEMENT> NOT ATOMIC. SQLCODE=-104, SQLSTATE=42601, DRIVER=4.25.17

So I can confirm that inline comma separated bulk inserts are not working on DB2 Z/OS (maybe you could feed it some props to get it working...)

if you want to add a class to an existing list of classes for an element:

element.Attributes.Add("class", element.Attributes["class"] + " " + sType);

I came across this, tot it would be nice to share...

What do you guys think?

$(document).ready(function() {
  window.mousemove = function(e) {
    p = $(e).position();  //remember $(e) - could be any html tag also.. 
    left = e.left;        //retrieving the left position of the div... 
    top = e.top;          //get the top position of the div... 
  }
});

and boom, there we have it..

For me, the problem was I was using a package that isn't included in package.json nor installed.

import { ToastrService } from 'ngx-toastr';

So when the compiler tried to compile this, it threw an error.

(I installed it locally, and when running a build on an external server the error was thrown)

None of the answers worked with fish shell (it doesn't have the variables $$ or $0).

This works for me (tested on sh, bash, fish, ksh, csh, true, tcsh, and zsh; openSUSE 13.2):

ps | tail -n 4 | sed -E '2,$d;s/.* (.*)/\1/'

This command outputs a string like bash. Here I'm only using ps, tail, and sed (without GNU extesions; try to add --posix to check it). They are all standard POSIX commands. I'm sure tail can be removed, but my sed fu is not strong enough to do this.

It seems to me, that this solution is not very portable as it doesn't work on OS X. :(

size_t is an unsigned variable, thus 'unsigned value = - 1' automatically makes it the largest possible value for size_t: 18446744073709551615

I had the same issue in AWS RDS. It was due to the Freeable Space (Hard Drive Storage Space) was Full. You need to increase your space, or remove some data.

XAMPP only offers MySQL (Database Server) & Apache (Webserver) in one setup and you can manage them with the xampp starter.

After the successful installation navigate to your xampp folder and execute the xampp-control.exe

Press the start Button at the mysql row.

Now you've successfully started mysql. Now there are 2 different ways to administrate your mysql server and its databases.

But at first you have to set/change the MySQL Root password. Start the Apache server and type localhost or 127.0.0.1 in your browser's address bar. If you haven't deleted anything from the htdocs folder the xampp status page appears. Navigate to security settings and change your mysql root password.

Now, you can browse to your phpmyadmin under http://localhost/phpmyadmin or download a windows mysql client for example navicat lite or mysql workbench. Install it and log in to your mysql server with your new root password.

PEP 8 defines that it is better to use the is operator when comparing singletons.

A small note about the efficiency of abovementioned methods:

 library(microbenchmark)

  microbenchmark(
    which("Feb" == month.abb)[[1]],
    which(month.abb %in% "Feb"))

  Unit: nanoseconds
   min     lq    mean median     uq  max neval
   891  979.0 1098.00   1031 1135.5 3693   100
   1052 1175.5 1339.74   1235 1390.0 7399  100

So, the best one is

    which("Feb" == month.abb)[[1]]

Make sure you allow 32 bits applications on IIS if you did deploy to IIS. You can define this on the settings of your current Application Pool.

Try this library:

https://github.com/avast/android-styled-dialogs

It's based on DialogFragments instead of AlertDialogs (like the one from @afollestad). The main advantage: Dialogs don't dismiss after rotation and callbacks still work.

You can create a new blank solution and add your different projects to it.

Kotlin version below (Updated version of @paul-burke response:

fun openPDFDocument(context: Context, filename: String) {
    //Create PDF Intent
    val pdfFile = File(Environment.getExternalStorageDirectory().absolutePath + "/" + filename)
    val pdfIntent = Intent(Intent.ACTION_VIEW)
    pdfIntent.setDataAndType(Uri.fromFile(pdfFile), "application/pdf")

__func__ is documented in the C++0x standard at section 8.4.1. In this case it's a predefined function local variable of the form:

static const char __func__[] = "function-name ";

where "function name" is implementation specfic. This means that whenever you declare a function, the compiler will add this variable implicitly to your function. The same is true of __FUNCTION__ and __PRETTY_FUNCTION__. Despite their uppercasing, they aren't macros. Although __func__ is an addition to C++0x

g++ -std=c++98 ....

will still compile code using __func__.

__PRETTY_FUNCTION__ and __FUNCTION__ are documented here http://gcc.gnu.org/onlinedocs/gcc-4.5.1/gcc/Function-Names.html#Function-Names. __FUNCTION__ is just another name for __func__. __PRETTY_FUNCTION__ is the same as __func__ in C but in C++ it contains the type signature as well.

Use the traceback module:

import sys
import traceback

try:
    assert True
    assert 7 == 7
    assert 1 == 2
    # many more statements like this
except AssertionError:
    _, _, tb = sys.exc_info()
    traceback.print_tb(tb) # Fixed format
    tb_info = traceback.extract_tb(tb)
    filename, line, func, text = tb_info[-1]

    print('An error occurred on line {} in statement {}'.format(line, text))
    exit(1)

    byte[] buffer = new byte[1024];  // buffer store for the stream
    int bytes; // bytes returned from read()

    // Keep listening to the InputStream until an exception occurs
    while (true) {
        try {
            // Read from the InputStream
            bytes = mmInStream.read(buffer);

            String TOKEN_ = new String(buffer, "UTF-8");

            String xx = TOKEN_.substring(0, bytes);

Looking at your example, I think ArrayBlockingQueue (or its siblings) may be of use. They look after the synchronisation for you, so threads can write to the queue or peek/take without additional synchronisation work on your part.

Remove the data from the adapter and call adapter.notifyDataSetChanged();

Ternary, conditional; tomato, tomatoh. What it's really valuable for is variable initialization. If (like me) you're fond of initializing variables where they are defined, the conditional ternary operator (for it is both) permits you to do that in cases where there is conditionality about its value. Particularly notable in final fields, but useful elsewhere, too.

e.g.:

public class Foo {
    final double    value;

    public Foo(boolean positive, double value) {
        this.value = positive ? value : -value;
    }
}

Without that operator - by whatever name - you would have to make the field non-final or write a function simply to initialize it. Actually, that's not right - it can still be initialized using if/else, at least in Java. But I find this cleaner.

In Android Studio 3.0 and later do this:

View > Tool Windows > Device File Explorer

I wrote a class to normalize the data in my dictionary. The 'element' in the NormalizeData class below, needs to be of dict type. And you need to replace in the __iterate() with either your custom class object or any other object type that you would like to normalize.

class NormalizeData:

    def __init__(self, element):
        self.element = element

    def execute(self):
        if isinstance(self.element, dict):
            self.__iterate()
        else:
            return

    def __iterate(self):
        for key in self.element:
            if isinstance(self.element[key], <ClassName>):
                self.element[key] = str(self.element[key])

            node = NormalizeData(self.element[key])
            node.execute()

In app.config file (or .exe.config) you can add or change the "receiveTimeout" property in binding. like this

<binding name="WebServiceName" receiveTimeout="00:00:59" />

I am Using common Servlet for every Html Form whether it has attachments or not.

                        key_values.put(fi.getFieldName(), fi.getString());
                    }
                }
            } catch (Exception ex) {
                System.out.println(ex);

foreach uses iterators under the hood anyway. It really is just syntactic sugar.

Consider the following program:

import java.util.List;
import java.util.ArrayList;

public class Whatever {
    private final List<Integer> list = new ArrayList<>();
    public void main() {
        for(Integer i : list) {
        }
    }
}

Let's compile it with javac Whatever.java,
And read the disassembled bytecode of main(), using javap -c Whatever:

public void main();
  Code:
     0: aload_0
     1: getfield      #4                  // Field list:Ljava/util/List;
     4: invokeinterface #5,  1            // InterfaceMethod java/util/List.iterator:()Ljava/util/Iterator;
     9: astore_1
    10: aload_1
    11: invokeinterface #6,  1            // InterfaceMethod java/util/Iterator.hasNext:()Z
    16: ifeq          32
    19: aload_1
    20: invokeinterface #7,  1            // InterfaceMethod java/util/Iterator.next:()Ljava/lang/Object;
    25: checkcast     #8                  // class java/lang/Integer
    28: astore_2
    29: goto          10
    32: return

We can see that foreach compiles down to a program which:

• Creates iterator using List.iterator()
• If Iterator.hasNext(): invokes Iterator.next() and continues loop

As for "why doesn't this useless loop get optimized out of the compiled code? we can see that it doesn't do anything with the list item": well, it's possible for you to code your iterable such that .iterator() has side-effects, or so that .hasNext() has side-effects or meaningful consequences.

You could easily imagine that an iterable representing a scrollable query from a database might do something dramatic on .hasNext() (like contacting the database, or closing a cursor because you've reached the end of the result set).

So, even though we can prove that nothing happens in the loop body… it is more expensive (intractable?) to prove that nothing meaningful/consequential happens when we iterate. The compiler has to leave this empty loop body in the program.

The best we could hope for would be a compiler warning. It's interesting that javac -Xlint:all Whatever.java does not warn us about this empty loop body. IntelliJ IDEA does though. Admittedly I have configured IntelliJ to use Eclipse Compiler, but that may not be the reason why.

HTTP COOKIES

Cookies are key/value pairs used by websites to store state information on the browser. Say you have a website (example.com), when the browser requests a webpage the website can send cookies to store information on the browser.

Browser request example:

GET /index.html HTTP/1.1
Host: www.example.com

Example answer from the server:

HTTP/1.1 200 OK
Content-type: text/html
Set-Cookie: foo=10
Set-Cookie: bar=20; Expires=Fri, 30 Sep 2011 11:48:00 GMT
... rest  of the response

Here two cookies foo=10 and bar=20 are stored on the browser. The second one will expire on 30 September. In each subsequent request the browser will send the cookies back to the server.

GET /spec.html HTTP/1.1
Host: www.example.com
Cookie: foo=10; bar=20
Accept: */*

SESSIONS: Server side cookies

Server side cookies are known as "sessions". The website in this case stores a single cookie on the browser containing a unique Session Identifier. Status information (foo=10 and bar=20 above) are stored on the server and the Session Identifier is used to match the request with the data stored on the server.

Examples of usage

You can use both sessions and cookies to store: authentication data, user preferences, the content of a chart in an e-commerce website, etc...

Pros and Cons

Below pros and cons of the solutions. These are the first that comes to my mind, there are surely others.

Cookie Pros:

• scalability: all the data is stored in the browser so each request can go through a load balancer to different webservers and you have all the information needed to fullfill the request;
• they can be accessed via javascript on the browser;
• not being on the server they will survive server restarts;
• RESTful: requests don't depend on server state

Cookie Cons:

• storage is limited to 80 KB (20 cookies, 4 KB each)
• secure cookies are not easy to implement: take a look at the paper A secure cookie protocol

Session Pros:

• generally easier to use, in PHP there's probably not much difference.
• unlimited storage

Session Cons:

• more difficult to scale
• on web server restarts you can lose all sessions or not depending on the implementation
• not RESTful

  $("select").prop("selectedIndex",$("select").prop("selectedIndex")+1)

Be careful, the solution proposed with $a = array_combine($a, $a); will not work for numeric values.

I for example wanted to have a memory array(128,256,512,1024,2048,4096,8192,16384) to be the keys as well as the values however PHP manual states:

If the input arrays have the same string keys, then the later value for that key will overwrite the previous one. If, however, the arrays contain numeric keys, the later value will not overwrite the original value, but will be appended.

So I solved it like this:

foreach($array as $key => $val) {
    $new_array[$val]=$val;
}

You're getting errors 'table liam does not exist' because the table's name is Liam which is not the same as liam. MySQL table names are case sensitive.

The short and straightforward answer would be because char[] is mutable while String objects are not.

Strings in Java are immutable objects. That is why they can't be modified once created, and therefore the only way for their contents to be removed from memory is to have them garbage collected. It will be only then when the memory freed by the object can be overwritten, and the data will be gone.

Now garbage collection in Java doesn't happen at any guaranteed interval. The String can thus persist in memory for a long time, and if a process crashes during this time, the contents of the string may end up in a memory dump or some log.

With a character array, you can read the password, finish working with it as soon as you can, and then immediately change the contents.

Your can do it like this in short hands.

        int[,] values=new int[2,3]{{2,4,5},{4,5,2}};

        for (int i = 0; i < values.GetLength(0); i++)
        {
            for (int k = 0; k < values.GetLength(1); k++) {
                Console.Write(values[i,k]);
            }

            Console.WriteLine();
        }

I only just wrote it for another issue and thought it may help either of you as well.

Usage:

• i.e. onclick="_DOM_Trackr(this);"

Parameters:

1. DOM-Object to trace
2. return/alert switch (optional, default=alert)

Source-Code:

function _DOM_Trackr(_elem,retn=false)
{
    var pathTrackr='';
    var $self=$(_elem).get(0);
    while($self && $self.tagName)
    {
        var $id=($($self).attr("id"))?('#'+$($self).attr("id")):'';
        var $nName=$self.tagName;
        pathTrackr=($nName.toLowerCase())+$id+((pathTrackr=='')?'':' > '+(pathTrackr));
        $self=$($self).parent().get(0);
    }
    if (retn)
    {
        return pathTrackr;
    }
    else
    {
        alert(pathTrackr);
    }
}

Instead of toJSON, you can use format function which always gives the correct date and time + GMT

This is the most robust display option. It takes a string of tokens and replaces them with their corresponding values.

Use CHAR:

=Char(34)&"This is in quotes"&Char(34)

Should evaluate to:

"This is in quotes"

function tinyFriends() {
    let myFriends = ["Mukit", "Ali", "Umor", "sabbir"]
    let smallestFridend = myFriends[0];
    for (i = 0; i < myFriends.length; i++) {
        if (myFriends[i] < smallestFridend) {
            smallestFridend = myFriends[i];
        }
    }
    return smallestFridend   
}

You can use this:

comment = Comment.objects.filter(pk=comment_id)

pixels = np.array(pixels) in this line you reassign pixels. So, it may not a list anyhow. Though pixels is not a list it has no attributes append. Does it make sense?

In jsFiddle by default the code you type into the script block is wrapped in a function executed on window.onload:

<script type='text/javascript'>//<![CDATA[ 
    window.onload = function () {
        function myFunc(id){
            alert(id);     
        }
    }
//]]>  
</script>

Because of this, your function myFunc is not in the global scope so is not available to your html buttons. By changing the option to No-wrap in <head> as Sergio suggests your code isn't wrapped:

<script type='text/javascript'>//<![CDATA[ 
    function myFunc(id){
       alert(id);     
    }
//]]>  
</script>

and so the function is in the global scope and available to your html buttons.

I have developed a solution with the freely available classes ( AnimatedGifEncoder, GifDecoder, and LWZEncoder) available for handling GIF Animation.
You can download the jgifcode jar and run the GifImageUtil class. Link: http://www.jgifcode.com

Had the same question. The other answers don't seem to address why close() is really necessary? Also, Op seemed to be struggling to figure out the preferred way to work with HttpClient, et al.

According to Apache:

// The underlying HTTP connection is still held by the response object
// to allow the response content to be streamed directly from the network socket.
// In order to ensure correct deallocation of system resources
// the user MUST call CloseableHttpResponse#close() from a finally clause.

In addition, the relationships go as follows:

HttpClient (interface)

implemented by:

CloseableHttpClient - ThreadSafe.

DefaultHttpClient - ThreadSafe BUT deprecated, use HttpClientBuilder instead.

HttpClientBuilder - NOT ThreadSafe, BUT creates ThreadSafe CloseableHttpClient.

• Use to create CUSTOM CloseableHttpClient.

HttpClients - NOT ThreadSafe, BUT creates ThreadSafe CloseableHttpClient.

• Use to create DEFAULT or MINIMAL CloseableHttpClient.

The preferred way according to Apache:

CloseableHttpClient httpclient = HttpClients.createDefault();

The example they give does httpclient.close() in the finally clause, and also makes use of ResponseHandler as well.

As an alternative, the way mkyong does it is a bit interesting, as well:

HttpClient client = HttpClientBuilder.create().build();

He doesn't show a client.close() call but I would think it is necessary, since client is still an instance of CloseableHttpClient.

OAuth(Open Authorization) is an open standard for access granting/deligation protocol. It used as a way for Internet users to grant websites or applications access to their information on other websites but without giving them the passwords. It does not deal with authentication.

Or

OAuth 2.0 is a protocol that allows a user to grant limited access to their resources on one site, to another site, without having to expose their credentials.

• Analogy 1: Many luxury cars today come with a valet key. It is a special key you give the parking attendant and unlike your regular key, will not allow the car to drive more than a mile or two. Some valet keys will not open the trunk, while others will block access to your onboard cell phone address book. Regardless of what restrictions the valet key imposes, the idea is very clever. You give someone limited access to your car with a special key, while using your regular key to unlock everything. src from auth0

• Analogy 2: Assume, we want to fill an application form for a bank account. Here Oauth works as, instead of filling the form by applicant, bank can fill the form using Adhaar or passport.

  Here the following three entities are involved:

  1. Applicant i.e. Owner
  2. Bank Account is OAuth Client, they need information
  3. Adhaar/Passport ID is OAuth Provider

I had faced the same xlrd.biffh.XLRDError: Unsupported format, or corrupt file: Expected BOF record; error and solved it by writing an XML to XLSX converter. The reason is that actually, xlrd does not support XML Spreadsheet (*.xml) i.e. NOT in XLS or XLSX format.

import pandas as pd
from bs4 import BeautifulSoup

def convert_to_xlsx():
    with open('sample.xls') as xml_file:
        soup = BeautifulSoup(xml_file.read(), 'xml')
        writer = pd.ExcelWriter('sample.xlsx')
        for sheet in soup.findAll('Worksheet'):
            sheet_as_list = []
            for row in sheet.findAll('Row'):
                sheet_as_list.append([cell.Data.text if cell.Data else '' for cell in row.findAll('Cell')])
            pd.DataFrame(sheet_as_list).to_excel(writer, sheet_name=sheet.attrs['ss:Name'], index=False, header=False)

        writer.save()

Programmatically, you can do this:

btn.BorderBrush = new SolidColorBrush(Colors.Transparent);

To have a query working in any locale settings, consider formatting the date yourself:

SELECT * 
  FROM testbed 
 WHERE start_date >= to_date('2012-01-01','YYYY-MM-DD')
   AND end_date <= to_date('2012-04-13','YYYY-MM-DD');

Updated below for ES6

March 2013 and ES5

This MDN document describes extending classes well:

https://developer.mozilla.org/en-US/docs/JavaScript/Introduction_to_Object-Oriented_JavaScript

In particular, here is now they handle it:

// define the Person Class
function Person() {}

Person.prototype.walk = function(){
  alert ('I am walking!');
};
Person.prototype.sayHello = function(){
  alert ('hello');
};

// define the Student class
function Student() {
  // Call the parent constructor
  Person.call(this);
}

// inherit Person
Student.prototype = Object.create(Person.prototype);

// correct the constructor pointer because it points to Person
Student.prototype.constructor = Student;

// replace the sayHello method
Student.prototype.sayHello = function(){
  alert('hi, I am a student');
}

// add sayGoodBye method
Student.prototype.sayGoodBye = function(){
  alert('goodBye');
}

var student1 = new Student();
student1.sayHello();
student1.walk();
student1.sayGoodBye();

// check inheritance
alert(student1 instanceof Person); // true 
alert(student1 instanceof Student); // true

Note that Object.create() is unsupported in some older browsers, including IE8:

If you are in the position of needing to support these, the linked MDN document suggests using a polyfill, or the following approximation:

function createObject(proto) {
    function ctor() { }
    ctor.prototype = proto;
    return new ctor();
}

Using this like Student.prototype = createObject(Person.prototype) is preferable to using new Person() in that it avoids calling the parent's constructor function when inheriting the prototype, and only calls the parent constructor when the inheritor's constructor is being called.

May 2017 and ES6

Thankfully, the JavaScript designers have heard our pleas for help and have adopted a more suitable way of approaching this issue.

MDN has another great example on ES6 class inheritance, but I'll show the exact same set of classes as above reproduced in ES6:

class Person {
    sayHello() {
        alert('hello');
    }

    walk() {
        alert('I am walking!');
    }
}

class Student extends Person {
    sayGoodBye() {
        alert('goodBye');
    }

    sayHello() {
        alert('hi, I am a student');
    }
}

var student1 = new Student();
student1.sayHello();
student1.walk();
student1.sayGoodBye();

// check inheritance
alert(student1 instanceof Person); // true 
alert(student1 instanceof Student); // true

Clean and understandable, just like we all want. Keep in mind, that while ES6 is pretty common, it's not supported everywhere:

Hardware

If a GPU device has, for example, 4 multiprocessing units, and they can run 768 threads each: then at a given moment no more than 4*768 threads will be really running in parallel (if you planned more threads, they will be waiting their turn).

Software

threads are organized in blocks. A block is executed by a multiprocessing unit. The threads of a block can be indentified (indexed) using 1Dimension(x), 2Dimensions (x,y) or 3Dim indexes (x,y,z) but in any case xyz <= 768 for our example (other restrictions apply to x,y,z, see the guide and your device capability).

Obviously, if you need more than those 4*768 threads you need more than 4 blocks. Blocks may be also indexed 1D, 2D or 3D. There is a queue of blocks waiting to enter the GPU (because, in our example, the GPU has 4 multiprocessors and only 4 blocks are being executed simultaneously).

Now a simple case: processing a 512x512 image

Suppose we want one thread to process one pixel (i,j).

We can use blocks of 64 threads each. Then we need 512*512/64 = 4096 blocks (so to have 512x512 threads = 4096*64)

It's common to organize (to make indexing the image easier) the threads in 2D blocks having blockDim = 8 x 8 (the 64 threads per block). I prefer to call it threadsPerBlock.

dim3 threadsPerBlock(8, 8);  // 64 threads

and 2D gridDim = 64 x 64 blocks (the 4096 blocks needed). I prefer to call it numBlocks.

dim3 numBlocks(imageWidth/threadsPerBlock.x,  /* for instance 512/8 = 64*/
              imageHeight/threadsPerBlock.y); 

The kernel is launched like this:

myKernel <<<numBlocks,threadsPerBlock>>>( /* params for the kernel function */ );       

Finally: there will be something like "a queue of 4096 blocks", where a block is waiting to be assigned one of the multiprocessors of the GPU to get its 64 threads executed.

In the kernel the pixel (i,j) to be processed by a thread is calculated this way:

uint i = (blockIdx.x * blockDim.x) + threadIdx.x;
uint j = (blockIdx.y * blockDim.y) + threadIdx.y;

=COUNTIFS(H5:H21000,">=100", H5:H21000,"<999")

This works for me

msg.BodyFormat = MailFormat.Html;

and then you can use html in your body

msg.Body = "<em>It's great to use HTML in mail!!</em>"

Hm, you may 'have to' quit the application if, say, your application requires an internet connection. You could display an alert and then do something like this:

if ([[UIApplication sharedApplication] respondsToSelector:@selector(terminate)]) {
    [[UIApplication sharedApplication] performSelector:@selector(terminate)];
} else {
    kill(getpid(), SIGINT); 
}

this worker for me

Function to hide the keyboard.

public static void hideKeyboard(Activity activity) {
    View view = activity.getCurrentFocus();

    if (view != null) {
        InputMethodManager inputManager = (InputMethodManager) activity.getSystemService(Context.INPUT_METHOD_SERVICE);

        inputManager.hideSoftInputFromWindow(view.getWindowToken(), InputMethodManager.HIDE_NOT_ALWAYS);
    }
}

Hide keyboard in AndroidManifext.xml file.

    android:name=".MainActivity"
    android:label="@string/app_name"
    android:theme="@style/AppTheme"

Another thing is - if your keys are very complicated sometimes you need to replace the places of the fields and it helps :

if this dosent work:

foreign key (ISBN, Title) references BookTitle (ISBN, Title)

Then this might work (not for this specific example but in general) :

foreign key (Title,ISBN) references BookTitle (Title,ISBN)

Updating to the latest version of Chrome (63.0.3239.84) via Help -> About fixed it for me.

(actually, I did had to switch to Offline and back to Online in the Network tab of developers tools to make the last errors go away.)

I found the code below does the trick. Sets a variable of the newly selected tab index

$("#tabs").tabs({
    activate: function (e, ui) {
        currentTabIndex =ui.newTab.index().toString();
    }
});

You can achieve 2 way data-binding in Nuxt/Vue like this:

Child.vue

<template>
    <input
      v-model="content"
       <!-- How you choose to emit the event is up to you could be @keydown or even inside a watch prop -->
      @keyup="$emit('update:dataFromParent', content)"
    />
</template>

<script>
export default {
  props: ["dataFromParent"],
  mounted() {
    this.content = this.dataFromParent;
  },
  data: () => ({
    content: "",
  }),
};
</script>

Parent.vue

<tenplate>
  <Child :dataFromParent.sync="text" />
</template>

<script>
import Child from "~/components/Child";

export default {
  components: {
    Child,
  },
  data: () => ({
    text: "Hello World!" ,
  }),
 
};
</script>

You can solve it with Joda Time:

Date utcDate = new Date(timezoneFrom.convertLocalToUTC(date.getTime(), false));
Date localDate = new Date(timezoneTo.convertUTCToLocal(utcDate.getTime()));

Java 8:

LocalDateTime localDateTime = LocalDateTime.parse("2007-12-03T10:15:30");
ZonedDateTime fromDateTime = localDateTime.atZone(
    ZoneId.of("America/Toronto"));
ZonedDateTime toDateTime = fromDateTime.withZoneSameInstant(
    ZoneId.of("Canada/Newfoundland"));

You need to animate the html, body

DEMO http://jsfiddle.net/kevinPHPkevin/8tLdq/1/

$("#button").click(function() {
    $('html, body').animate({
        scrollTop: $("#myDiv").offset().top
    }, 2000);
});

Try this

using (Image image = Image.FromFile(Path))
{
    using (MemoryStream m = new MemoryStream())
    {
        image.Save(m, image.RawFormat);
        byte[] imageBytes = m.ToArray();

        // Convert byte[] to Base64 String
        string base64String = Convert.ToBase64String(imageBytes);
        return base64String;
    }
}

For convenience, you can create a wrapper class around ResultSet that returns null values when ResultSet ordinarily would not.

public final class ResultSetWrapper {

    private final ResultSet rs;

    public ResultSetWrapper(ResultSet rs) {
        this.rs = rs;
    }

    public ResultSet getResultSet() {
        return rs;
    }

    public Boolean getBoolean(String label) throws SQLException {
        final boolean b = rs.getBoolean(label);
        if (rs.wasNull()) {
            return null;
        }
        return b;
    }

    public Byte getByte(String label) throws SQLException {
        final byte b = rs.getByte(label);
        if (rs.wasNull()) {
            return null;
        }
        return b;
    }

    // ...

}

In theory SMTP can be handled by either TCP, UDP, or some 3rd party protocol.

As defined in RFC 821, RFC 2821, and RFC 5321:

SMTP is independent of the particular transmission subsystem and requires only a reliable ordered data stream channel.

In addition, the Internet Assigned Numbers Authority has allocated port 25 for both TCP and UDP for use by SMTP.

In practice however, most if not all organizations and applications only choose to implement the TCP protocol. For example, in Microsoft's port listing port 25 is only listed for TCP and not UDP.

The big difference between TCP and UDP that makes TCP ideal here is that TCP checks to make sure that every packet is received and re-sends them if they are not whereas UDP will simply send packets and not check for receipt. This makes UDP ideal for things like streaming video where every single packet isn't as important as keeping a continuous flow of packets from the server to the client.

Considering SMTP, it makes more sense to use TCP over UDP. SMTP is a mail transport protocol, and in mail every single packet is important. If you lose several packets in the middle of the message the recipient might not even receive the message and if they do they might be missing key information. This makes TCP more appropriate because it ensures that every packet is delivered.

You can use java.util.concurrent.TimeUnit library which internally uses Thread.sleep. The syntax should look like this :

@Test
public void testExipres(){
    SomeCacheObject sco = new SomeCacheObject();
    sco.putWithExipration("foo", 1000);

    TimeUnit.MINUTES.sleep(2);

    assertNull(sco.getIfNotExipred("foo"));
}

This library provides more clear interpretation for time unit. You can use 'HOURS'/'MINUTES'/'SECONDS'.

Use intptr_t and uintptr_t.

To ensure it is defined in a portable way, you can use code like this:

#if defined(__BORLANDC__)
    typedef unsigned char uint8_t;
    typedef __int64 int64_t;
    typedef unsigned long uintptr_t;
#elif defined(_MSC_VER)
    typedef unsigned char uint8_t;
    typedef __int64 int64_t;
#else
    #include <stdint.h>
#endif

Just place that in some .h file and include wherever you need it.

Alternatively, you can download Microsoft’s version of the stdint.h file from here or use a portable one from here.

This question has many, many duplicates, including questions not mentioning the Chai assertion library. Here are the basics collected together:

The assertion must call the function, instead of it evaluating immediately.

assert.throws(x.y.z);      
   // FAIL.  x.y.z throws an exception, which immediately exits the
   // enclosing block, so assert.throw() not called.
assert.throws(()=>x.y.z);  
   // assert.throw() is called with a function, which only throws
   // when assert.throw executes the function.
assert.throws(function () { x.y.z });   
   // if you cannot use ES6 at work
function badReference() { x.y.z }; assert.throws(badReference);  
   // for the verbose
assert.throws(()=>model.get(z));  
   // the specific example given.
homegrownAssertThrows(model.get, z);
   //  a style common in Python, but not in JavaScript

You can check for specific errors using any assertion library:

Node

  assert.throws(() => x.y.z);
  assert.throws(() => x.y.z, ReferenceError);
  assert.throws(() => x.y.z, ReferenceError, /is not defined/);
  assert.throws(() => x.y.z, /is not defined/);
  assert.doesNotThrow(() => 42);
  assert.throws(() => x.y.z, Error);
  assert.throws(() => model.get.z, /Property does not exist in model schema./)

Should

  should.throws(() => x.y.z);
  should.throws(() => x.y.z, ReferenceError);
  should.throws(() => x.y.z, ReferenceError, /is not defined/);
  should.throws(() => x.y.z, /is not defined/);
  should.doesNotThrow(() => 42);
  should.throws(() => x.y.z, Error);
  should.throws(() => model.get.z, /Property does not exist in model schema./)

Chai Expect

  expect(() => x.y.z).to.throw();
  expect(() => x.y.z).to.throw(ReferenceError);
  expect(() => x.y.z).to.throw(ReferenceError, /is not defined/);
  expect(() => x.y.z).to.throw(/is not defined/);
  expect(() => 42).not.to.throw();
  expect(() => x.y.z).to.throw(Error);
  expect(() => model.get.z).to.throw(/Property does not exist in model schema./);

You must handle exceptions that 'escape' the test

it('should handle escaped errors', function () {
  try {
    expect(() => x.y.z).not.to.throw(RangeError);
  } catch (err) {
    expect(err).to.be.a(ReferenceError);
  }
});

This can look confusing at first. Like riding a bike, it just 'clicks' forever once it clicks.

Or rather easily:

mvn spring-boot:run -Dspring-boot.run.profiles={profile_name}

conda create -n py37 -c anaconda anaconda=5.3

seems to be working.

I found two really simple ways to do that:

$ git status | head -1 | cut -d ' ' -f 4

and

$ git branch | grep "*" | cut -d ' ' -f 2

Your current solution does not work because $time is a string - it needs to be a Unix timestamp. You can do this instead:

$unix_time = strtotime('January 1 2010 '.$time); // create a unix timestamp
$startTime date( "H:i", strtotime('-30 minutes', $unix_time) );
$endTime date( "H:i", strtotime('+30 minutes', $unix_time) );

While there are suggestions above for "doing it the python way", if one wants to really have a logic based on EOF, then I suppose using exception handling is the way to do it --

try:
    line = raw_input()
    ... whatever needs to be done incase of no EOF ...
except EOFError:
    ... whatever needs to be done incase of EOF ...

Example:

$ echo test | python -c "while True: print raw_input()"
test
Traceback (most recent call last):
  File "<string>", line 1, in <module> 
EOFError: EOF when reading a line

Or press Ctrl-Z at a raw_input() prompt (Windows, Ctrl-Z Linux)

The cool thing about the new Google Recaptcha is that the validation is now completely encapsulated in the widget. That means, that the widget will take care of asking questions, validating responses all the way till it determines that a user is actually a human, only then you get a g-recaptcha-response value.

But that does not keep your site safe from HTTP client request forgery.

Anyone with HTTP POST knowledge could put random data inside of the g-recaptcha-response form field, and foll your site to make it think that this field was provided by the google widget. So you have to validate this token.

In human speech it would be like,

• Your Server: Hey Google, there's a dude that tells me that he's not a robot. He says that you already verified that he's a human, and he told me to give you this token as a proof of that.
• Google: Hmm... let me check this token... yes I remember this dude I gave him this token... yeah he's made of flesh and bone let him through.
• Your Server: Hey Google, there's another dude that tells me that he's a human. He also gave me a token.
• Google: Hmm... it's the same token you gave me last time... I'm pretty sure this guy is trying to fool you. Tell him to get off your site.

Validating the response is really easy. Just make a GET Request to

https://www.google.com/recaptcha/api/siteverify?secret=your_secret&response=response_string&remoteip=user_ip_address

And replace the response_string with the value that you earlier got by the g-recaptcha-response field.

You will get a JSON Response with a success field.

More information here: https://developers.google.com/recaptcha/docs/verify

Edit: It's actually a POST, as per documentation here.

for others there are a solution for any API level , you can place a item on top of each other example :

<?xml version="1.0" encoding="utf-8"?>
<layer-list xmlns:android="http://schemas.android.com/apk/res/android" >

<!-- my firt item with 4 corners radius(8dp)
 -->
    <item>
        <shape>
            <solid
                android:angle="270.0"
                android:color="#3D689A" />

            <corners android:topLeftRadius="8dp" />
        </shape>
    </item>
<!-- my second item is on top right for a fake corner radius(0dp)
 -->
    <item
        android:bottom="30dp"
        android:left="50dp">
        <shape>
            <solid android:color="#5C83AF" />
        </shape>
    </item>
<!-- my third item is on bottom left for a fake corner radius(0dp)
 -->
    <item
        android:right="50dp"
        android:top="30dp">
        <shape>
            <solid android:color="#5C83AF" />
        </shape>
    </item>

</layer-list>

the result with light color to show you the three items :

the final result :

Best regards.

If your question was "why doesn't this cmd script fragment work?" then the answer is that for /f iterates over lines. The delims split lines into fields, but you're only capturing the first field in %%P. There is no way to capture an arbitrary number of fields with a for /f loop.

You can use If function Write in the cell where you want to input the date the following formula: =IF(MODIFIED-CELLNUMBER<>"",IF(CELLNUMBER-WHERE-TO-INPUT-DATE="",NOW(),CELLNUMBER-WHERE-TO-INPUT-DATE),"")

Don't reinvent the wheel. Use json-framework or something similar.

If you do decide to use json-framework, here's how you would parse a JSON string into an NSDictionary:

SBJsonParser* parser = [[[SBJsonParser alloc] init] autorelease];
// assuming jsonString is your JSON string...
NSDictionary* myDict = [parser objectWithString:jsonString];

// now you can grab data out of the dictionary using objectForKey or another dictionary method

The call to getTableCellRendererComponent(...) includes the value of the cell for which a renderer is sought.

You can use that value to compute a color. If you're also using an AbstractTableModel, you can provide a value of arbitrary type to your renderer.

Once you have a color, you can setBackground() on the component that you're returning.

Jenkins Pipeline also provides the current build number as the property number of the currentBuild. It can be read as currentBuild.number.

For example:

// Scripted pipeline
def buildNumber = currentBuild.number

// Declarative pipeline
echo "Build number is ${currentBuild.number}"

Other properties of currentBuild are described in the Pipeline Syntax: Global Variables page that is included on each Pipeline job page. That page describes the global variables available in the Jenkins instance based on the current plugins.

This solution requires you to know exact sizes of covered object.

Try this:

//KITKAT
i = new Intent(Intent.ACTION_PICK,android.provider.MediaStore.Images.Media.EXTERNAL_CONTENT_URI);
startActivityForResult(i, CHOOSE_IMAGE_REQUEST);

Use the following in the onActivityResult:

Uri selectedImageURI = data.getData();
input = c.getContentResolver().openInputStream(selectedImageURI);
BitmapFactory.decodeStream(input , null, opts);

Updated package.json:

"build": {
  "appId": "com.my-website.my-app",
  "productName": "MyApp",
  "copyright": "Copyright © 2019 ${author}",
  "mac": {
    "icon": "./public/icons/mac/icon.icns",     <---------- set Mac Icons
    "category": "public.app-category.utilities"
  },
  "win": {
    "icon": "./public/icons/png/256x256.png" <---------- set Win Icon
  },
  "files": [
    "./build/**/*",
    "./dist/**/*",

    "*.js"
  ],
  "directories": {
    "buildResources": "public" <---------- folder where placed icons
  }
},

After build application you can see icons. This solution don't show icons in developer mode. I don't setup icons in new BrowserWindow().

this question asked in 2009 but i want to share my codes:

    Public Function RowSearch(ByVal dttable As DataTable, ByVal searchcolumns As String()) As DataTable

    Dim x As Integer
    Dim y As Integer

    Dim bln As Boolean

    Dim dttable2 As New DataTable
    For x = 0 To dttable.Columns.Count - 1
        dttable2.Columns.Add(dttable.Columns(x).ColumnName)
    Next

    For x = 0 To dttable.Rows.Count - 1
        For y = 0 To searchcolumns.Length - 1
            If String.IsNullOrEmpty(searchcolumns(y)) = False Then
                If searchcolumns(y) = CStr(dttable.Rows(x)(y + 1) & "") & "" Then
                    bln = True
                Else
                    bln = False
                    Exit For
                End If
            End If
        Next
        If bln = True Then
            dttable2.Rows.Add(dttable.Rows(x).ItemArray)
        End If
    Next

    Return dttable2


End Function

Solution without try&catch and without new imports:

if len(driver.find_elements_by_id('blah')) > 0: #pay attention: find_element*s*
    driver.find_element_by_id('blah').click #pay attention: find_element

I think the Key and IV used for encryption using command line and decryption using your program are not same.

Please note that when you use the "-k" (different from "-K"), the input given is considered as a password from which the key is derived. Generally in this case, there is no need for the "-iv" option as both key and password will be derived from the input given with "-k" option.

It is not clear from your question, how you are ensuring that the Key and IV are same between encryption and decryption.

In my suggestion, better use "-K" and "-iv" option to explicitly specify the Key and IV during encryption and use the same for decryption. If you need to use "-k", then use the "-p" option to print the key and iv used for encryption and use the same in your decryption program.

Strtr replaces single characters instead of strings, so it's a good solution for this example. Supposedly strtr is faster than str_replace (but for this use case they're both immeasurably fast).

echo strtr('Alex Newton',' ','_');
//outputs: Alex_Newton

There's no magical solution of displaying something outside an overflow hidden container.

A similar effect can be achieved by having an absolute positioned div that matches the size of its parent by positioning it inside your current relative container (the div you don't wish to clip should be outside this div):

#1 .mask {
  width: 100%;
  height: 100%;
  position: absolute;
  z-index: 1;
  overflow: hidden;
}

Take in mind that if you only have to clip content on the x axis (which appears to be your case, as you only have set the div's width), you can use overflow-x: hidden.

import operator
sortedlist = sorted(reader, key=operator.itemgetter(3), reverse=True)

or use lambda

sortedlist = sorted(reader, key=lambda row: row[3], reverse=True)

You can try Dummynet, it can simulates queue and bandwidth limitations, delays, packet losses, and multipath effects

You can use preg_replace in this case;

$res = preg_replace("/[^0-9]/", "", "Every 6 Months" );

$res return 6 in this case.

If want also to include decimal separator or thousand separator check this example:

$res = preg_replace("/[^0-9.]/", "", "$ 123.099");

$res returns "123.099" in this case

Include period as decimal separator or thousand separator: "/[^0-9.]/"

Include coma as decimal separator or thousand separator: "/[^0-9,]/"

Include period and coma as decimal separator and thousand separator: "/[^0-9,.]/"

Non-blocking, multi-threaded example:

As blocking on keyboard input (since the input() function blocks) is frequently not what we want to do (we'd frequently like to keep doing other stuff), here's a very-stripped-down multi-threaded example to demonstrate how to keep running your main application while still reading in keyboard inputs whenever they arrive.

This works by creating one thread to run in the background, continually calling input() and then passing any data it receives to a queue.

In this way, your main thread is left to do anything it wants, receiving the keyboard input data from the first thread whenever there is something in the queue.

1. Bare Python 3 code example (no comments):

import threading
import queue
import time

def read_kbd_input(inputQueue):
    print('Ready for keyboard input:')
    while (True):
        input_str = input()
        inputQueue.put(input_str)

def main():
    EXIT_COMMAND = "exit"
    inputQueue = queue.Queue()

    inputThread = threading.Thread(target=read_kbd_input, args=(inputQueue,), daemon=True)
    inputThread.start()

    while (True):
        if (inputQueue.qsize() > 0):
            input_str = inputQueue.get()
            print("input_str = {}".format(input_str))

            if (input_str == EXIT_COMMAND):
                print("Exiting serial terminal.")
                break
            
            # Insert your code here to do whatever you want with the input_str.

        # The rest of your program goes here.

        time.sleep(0.01) 
    print("End.")

if (__name__ == '__main__'): 
    main()

2. Same Python 3 code as above, but with extensive explanatory comments:

The Python Queue library is thread-safe:

Note that Queue.put() and Queue.get() and other Queue class methods are thread-safe! That means they implement all the internal locking semantics required for inter-thread operations, so each function call in the queue class can be considered as a single, atomic operation. See the notes at the top of the documentation: https://docs.python.org/3/library/queue.html (emphasis added):

The queue module implements multi-producer, multi-consumer queues. It is especially useful in threaded programming when information must be exchanged safely between multiple threads. The Queue class in this module implements all the required locking semantics.

1. PySerial non-blocking read loop

This code moves up the text field you are editing so that you can view it in Swift 3 for this answer you also have to make your view a UITextFieldDelegate:

var moveValue: CGFloat!
var moved: Bool = false
var activeTextField = UITextField()

func textFieldDidBeginEditing(_ textField: UITextField) {
    self.activeTextField = textField
}
func textFieldDidEndEditing(_ textField: UITextField) {
    if moved == true{
    self.animateViewMoving(up: false, moveValue: moveValue )
        moved = false
    }
}
func animateViewMoving (up:Bool, moveValue :CGFloat){
    let movementDuration:TimeInterval = 0.3
    let movement:CGFloat = ( up ? -moveValue : moveValue)

    UIView.beginAnimations("animateView", context: nil)
    UIView.setAnimationBeginsFromCurrentState(true)
    UIView.setAnimationDuration(movementDuration)

    self.view.frame = self.view.frame.offsetBy(dx: 0, dy: movement)
    UIView.commitAnimations()
}

And then in viewDidLoad:

NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillShow), name: .UIKeyboardWillShow, object: nil)

Which calls (outside viewDidLoad):

func keyboardWillShow(notification: Notification) {
    if let keyboardSize = (notification.userInfo?[UIKeyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue {
        let keyboardHeight = keyboardSize.height
        if (view.frame.size.height-self.activeTextField.frame.origin.y) - self.activeTextField.frame.size.height < keyboardHeight{
            moveValue = keyboardHeight - ((view.frame.size.height-self.activeTextField.frame.origin.y) - self.activeTextField.frame.size.height)
            self.animateViewMoving(up: true, moveValue: moveValue )
            moved = true
        }
    }
}

The bottom statement is equivalent to:

.half {
   flex-grow: 0;
   flex-shrink: 0;
   flex-basis: 50%;
}

Which, in this case, would be equivalent as the box is not allowed to flex and therefore retains the initial width set by flex-basis.

Flex-basis defines the default size of an element before the remaining space is distributed so if the element were allowed to flex (grow/shrink) it may not be 50% of the width of the page.

I've found that I regularly return to https://css-tricks.com/snippets/css/a-guide-to-flexbox/ for help regarding flexbox :)

First check - is the working directory the directory that the application is running in:

• Right-click on your project and select Properties.
• Click the Debug tab.
• Confirm that the Working directory is either empty or equal to the bin\debug directory.

If this isn't the problem, then ask if Autodesk.Navisworks.Timeliner.dll is requiring another DLL which is not there. If Timeliner.dll is not a .NET assembly, you can determine the required imports using the command utility DUMPBIN.

dumpbin /imports Autodesk.Navisworks.Timeliner.dll

If it is a .NET assembly, there are a number of tools that can check dependencies.

Reflector has already been mentioned, and I use JustDecompile from Telerik.

I have encountered the very similar problem today. For some reason IntelliJ IDEA haven't included Spring Security jar files while deploying the application. I think I should agree with the majority of posters here.

Walkthough on what is MUL, PRI and UNI in MySQL?

From the MySQL 5.7 documentation:

• If Key is PRI, the column is a PRIMARY KEY or is one of the columns in a multiple-column PRIMARY KEY.
• If Key is UNI, the column is the first column of a UNIQUE index. (A UNIQUE index permits multiple NULL values, but you can tell whether the column permits NULL by checking the Null field.)
• If Key is MUL, the column is the first column of a nonunique index in which multiple occurrences of a given value are permitted within the column.

Live Examples

Control group, this example has neither PRI, MUL, nor UNI:

mysql> create table penguins (foo INT);
Query OK, 0 rows affected (0.01 sec)

mysql> desc penguins;
+-------+---------+------+-----+---------+-------+
| Field | Type    | Null | Key | Default | Extra |

+-------+---------+------+-----+---------+-------+
1 row in set (0.00 sec)

A table with one column and an index on the one column has a MUL:

Various ways to create a branch in git from another branch:

This answer adds some additional insight, not already present in the existing answers, regarding just the title of the question itself (Create a branch in Git from another branch), but does not address the more narrow specifics of the question which already have sufficient answers here.

I'm adding this because I really needed to know how to do #1 below just now (create a new branch from a branch I do NOT have checked out), and it wasn't obvious how to do it, and Google searches led to here as a top search result. So, I'll share my findings here. This isn't touched upon well, if at all, by any other answer here.

While I'm at it, I'll also add my other most-common git branch commands I use in my regular workflow, below.

1. To create a new branch from a branch you do NOT have checked out:

Create branch2 from branch1 while you have any branch whatsoever checked out (ex: let's say you have master checked out):

git branch branch2 branch1

The general format is:

git branch <new_branch> [from_branch]

man git branch shows it as:

git branch [--track | --no-track] [-l] [-f] <branchname> [<start-point>]

2. To create a new branch from the branch you DO have checked out:

git branch new_branch

This is great for making backups before rebasing, squashing, hard resetting, etc.--before doing anything which could mess up your branch badly.

Ex: I'm on feature_branch1, and I'm about to squash 20 commits into 1 using git rebase -i master. In case I ever want to "undo" this, let's back up this branch first! I do this ALL...THE...TIME and find it super helpful and comforting to know I can always easily go back to this backup branch and re-branch off of it to try again in case I mess up feature_branch1 in the process:

git branch feature_branch1_BAK_20200814-1320hrs_about_to_squash

The 20200814-1120hrs part is the date and time in format YYYYMMDD-HHMMhrs, so that would be 13:20hrs (1:20pm) on 14 Aug. 2020. This way I have an easy way to find my backup branches until I'm sure I'm ready to delete them. If you don't do this and you mess up badly, you have to use git reflog to go find your branch prior to messing it up, which is much harder, more stressful, and more error-prone.

3. To create and check out a new branch from the branch you DO have checked out:

git checkout -b new_branch

4. To rename a branch

Just like renaming a regular file or folder in the terminal, git considered "renaming" to be more like a 'm'ove command, so you use git branch -m to rename a branch. Here's the general format:

git branch -m <old_name> <new_name>

man git branch shows it like this:

git branch (-m | -M) [<oldbranch>] <newbranch>

Example: let's rename branch_1 to branch_1.5:

git branch -m branch_1 branch_1.5

You find the differences explained in the detailed PHP manual on the page of require:

require is identical to include except upon failure it will also produce a fatal E_COMPILE_ERROR level error. In other words, it will halt the script whereas include only emits a warning (E_WARNING) which allows the script to continue.

See @efritz's answer for an example

Pass a duration to show() and hide():

When a duration is provided, .show() becomes an animation method.

E.g. element.delay(1000).show(0)

DEMO

Exception handling is included in free standing implementations.

The reason of this is that you possibly use gcc to compile your code. If you compile with the option -### you will notice it is missing the linker-option -lstdc++ when it invokes the linker process . Compiling with g++ will include that library, and thus the symbols defined in it.

How to dynamically alter the minDate (after init)

The above answers address how to set the default minDate at init, but the question was actually how to dynamically alter the minDate, below I also clarify How to set the default minDate.

All that was wrong with the original question was that the minDate value being set should have been a string (don't forget the quotes):

$('#datePickerId').datepicker('option', 'minDate', '3');

minDate also accepts a date object and a common use is to have an end date you are trying to calculate so something like this could be useful:

$('#datePickerId').datepicker(
    'option', 'minDate', new Date($(".datePop.start").val())
);

How to set the default minDate (at init)

Just answering this for best practice; the minDate option expects one of:

1. a string in the current dateFormat OR
2. number of days from today (e.g. +7) OR
3. string of values and periods ('y' for years, 'm' for months, 'w' for weeks, 'd' for days, e.g. '-1y -1m')

@bogart setting the string to "0" is a solution as it satisfies option 2 above

$('#datePickerId').datepicker('minDate': '3');

      <param name="File" value="sample.log"/>
      <layout class="org.apache.log4j.PatternLayout">
         <param name="ConversionPattern" value="%d %-5p  [%c{1}] %m %n" />
      </layout>
   </appender>

  <root> 
    <priority value ="debug" /> 
    <appender-ref ref="fileAppender" /> 
  </root> 

</log4j:configuration>

Log4j can be a bit confusing. So lets try to understand what is going on in this file: In log4j you have two basic constructs appenders and loggers.

Appenders define how and where things are appended. Will it be logged to a file, to the console, to a database, etc.? In this case you are specifying that log statements directed to fileAppender will be put in the file sample.log using the pattern specified in the layout tags. You could just as easily create a appender for the console or the database. Where the console appender would specify things like the layout on the screen and the database appender would have connection details and table names.

Loggers respond to logging events as they bubble up. If an event catches the interest of a specific logger it will invoke its attached appenders. In the example below you have only one logger the root logger - which responds to all logging events by default. In addition to the root logger you can specify more specific loggers that respond to events from specific packages. These loggers can have their own appenders specified using the appender-ref tags or will otherwise inherit the appenders from the root logger. Using more specific loggers allows you to fine tune the logging level on specific packages or to direct certain packages to other appenders.

So what this file is saying is:

1. Create a fileAppender that logs to file sample.log
2. Attach that appender to the root logger.
3. The root logger will respond to any events at least as detailed as 'debug' level
4. The appender is configured to only log events that are at least as detailed as 'info'

The net out is that if you have a logger.debug("blah blah") in your code it will get ignored. A logger.info("Blah blah"); will output to sample.log.

The snippet below could be added to the file above with the log4j tags. This logger would inherit the appenders from <root> but would limit the all logging events from the package org.springframework to those logged at level info or above.

  <!-- Example Package level Logger -->
    <logger name="org.springframework">
        <level value="info"/>
    </logger>   

Based on the date of this question the original poster wouldn't have been using Windows Subsystem for Linux. But if you are, and you get the same error, the following alternative works:

clip.exe < ~/.ssh/id_rsa.pub

Thanks to this page for pointing out Windows' clip.exe (and you have to type the ".exe") can be run from the bash shell.

If I understood your problem correctly, $(this).parents('.box').children('.something1') Is this what you are looking for?

Another solution:

import collections


def defaultargs(func, defaults):
    def wrapper(*args, **kwargs):
        for key, value in (x for x in defaults[len(args):] if len(x) == 2):
            kwargs.setdefault(key, value)
        return func(*args, **kwargs)
    return wrapper


def namedtuple(name, fields):
    NamedTuple = collections.namedtuple(name, [x[0] for x in fields])
    NamedTuple.__new__ = defaultargs(NamedTuple.__new__, [(NamedTuple,)] + fields)
    return NamedTuple

Usage:

>>> Node = namedtuple('Node', [
...     ('val',),
...     ('left', None),
...     ('right', None),
... ])
__main__.Node

>>> Node(1)
Node(val=1, left=None, right=None)

>>> Node(1, 2, right=3)
Node(val=1, left=2, right=3)

Try this on for size:

String properCase (String inputVal) {
    // Empty strings should be returned as-is.

    if (inputVal.length() == 0) return "";

    // Strings with only one character uppercased.

    if (inputVal.length() == 1) return inputVal.toUpperCase();

    // Otherwise uppercase first letter, lowercase the rest.

    return inputVal.substring(0,1).toUpperCase()
        + inputVal.substring(1).toLowerCase();
}

It basically handles special cases of empty and one-character string first and correctly cases a two-plus-character string otherwise. And, as pointed out in a comment, the one-character special case isn't needed for functionality but I still prefer to be explicit, especially if it results in fewer useless calls, such as substring to get an empty string, lower-casing it, then appending it as well.

If you ever need to transfer the zipped content via network or store it as text, you have to use Base64 encoder(such as apache commons codec Base64) to convert the byte array to a Base64 String, and decode the string back to byte array at remote client. Found an example at Use Zip Stream and Base64 Encoder to Compress Large String Data!

To delimit by a tab you can use the sep argument of to_csv:

df.to_csv(file_name, sep='\t')

To use a specific encoding (e.g. 'utf-8') use the encoding argument:

df.to_csv(file_name, sep='\t', encoding='utf-8')

Try the solution from this question: How can I get an direct Instagram link from a twitter entity?

You can get just the image by appending /media/ to the URL. Using your

You can even specify a size,

One of t (thumbnail), m (medium), l (large). Defaults to m.

So for a thumbnail: http://instagr.am/p/QC8hWKL_4K/media/?size=t

Once you've found your jar through mvnrepository.com, hover the "download (JAR)" link, and you'll see the link to the repository which contains your jar (you can probably Right clic and "Copy link URL" to get the URL, what ever your browser is).

Then, you have to add this repository to the repositories used by your project, in your pom.xml :

<project>
  ...
  <repositories>
    <repository>
      <id>my-alternate-repository</id>
      <url>http://myrepo.net/repo</url>
    </repository>
  </repositories>
  ...
</project>

EDIT : now MVNrepository.com has evolved : You can find the link to the repository in the "Repositories" section :

I have seen comments in INI files, so yes. Please refer to this Wikipedia article. I could not find an official specification, but that is the correct syntax for comments, as many game INI files had this as I remember.

Edit

The API returns the Value and the Comment (forgot to mention this in my reply), just construct and example INI file and call the API on this (with comments) and you can see how this is returned.

Assign after the EXEC token:

DECLARE @returnValue INT

EXEC @returnValue = SP_One

Try:

<xsl:value-of select="count(preceding-sibling::*) + 1" />

Edit - had a brain freeze there, position() is more straightforward!

Below gives me opposite of what you have. (Notice Group column)

SELECT
    *
FROM
    myTable
GROUP BY
    Group_value,
    ID
ORDER BY
    count(Group_value)

Let me know if this is fine with you...

I am trying to get what you want too...

Instructions

First, insert these lines wherever you want within your newsletter code. Then:

1. Change "INSERT URL" to whatever website holds the shared content.
2. Change "INSERT TITLE" to the title of the article.
3. Change "INSERT SUMMARY" to a short summary of the article.
4. Change "INSERT IMAGE URL" to an image that will be shared with the rest of the content.
5. Change "INSERT DOMAIN NAME" to your domain name.
6. Change "INSERT PUBLISHERID" to your publisher ID (if you have an account, if not, remove "[INSERT PUBLISHERID]" or sign up!)

If you are using this on an email newsletter, make sure you add our sharing buttons to the destination page. This will ensure that you get complete sharing analytics for your page. Make sure you replace "INSERT PUBLISHERID" with your own.

My solution neither uses any third-party library nor forces you to call custom methods on SQLiteOpenHelper subclass to initialize the database on creation. It also takes care of database upgrades as well. All that needs to be done is to subclass SQLiteOpenHelper.

Prerequisite:

1. The database that you wish to ship with the app. It should contain a 1x1 table named android_metadata with an attribute locale having the value en_US in addition to the tables unique to your app.

Subclassing SQLiteOpenHelper:

1. Subclass SQLiteOpenHelper.
2. Create a private method within the SQLiteOpenHelper subclass. This method contains the logic to copy database contents from the database file in the 'assets' folder to the database created in the application package context.
3. Override onCreate, onUpgrade and onOpen methods of SQLiteOpenHelper.

Enough said. Here goes the SQLiteOpenHelper subclass:

public class PlanDetailsSQLiteOpenHelper extends SQLiteOpenHelper {
    private static final String TAG = "SQLiteOpenHelper";

    private final Context context;
    private static final int DATABASE_VERSION = 1;
    private static final String DATABASE_NAME = "my_custom_db";

    private boolean createDb = false, upgradeDb = false;

    public PlanDetailsSQLiteOpenHelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
        this.context = context;
    }

    /**
     * Copy packaged database from assets folder to the database created in the
     * application package context.
     * 
     * @param db
     *            The target database in the application package context.
     */
    private void copyDatabaseFromAssets(SQLiteDatabase db) {
        Log.i(TAG, "copyDatabase");
        InputStream myInput = null;
        OutputStream myOutput = null;
        try {
            // Open db packaged as asset as the input stream
            myInput = context.getAssets().open("path/to/shipped/db/file");

            // Open the db in the application package context:
            myOutput = new FileOutputStream(db.getPath());

            // Transfer db file contents:
            byte[] buffer = new byte[1024];
            int length;
            while ((length = myInput.read(buffer)) > 0) {
                myOutput.write(buffer, 0, length);
            }
            myOutput.flush();

            // Set the version of the copied database to the current
            // version:
            SQLiteDatabase copiedDb = context.openOrCreateDatabase(
                DATABASE_NAME, 0, null);
            copiedDb.execSQL("PRAGMA user_version = " + DATABASE_VERSION);
            copiedDb.close();

        } catch (IOException e) {
            e.printStackTrace();
            throw new Error(TAG + " Error copying database");
        } finally {
            // Close the streams
            try {
                if (myOutput != null) {
                    myOutput.close();
                }
                if (myInput != null) {
                    myInput.close();
                }
            } catch (IOException e) {
                e.printStackTrace();
                throw new Error(TAG + " Error closing streams");
            }
        }
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        Log.i(TAG, "onCreate db");
        createDb = true;
    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        Log.i(TAG, "onUpgrade db");
        upgradeDb = true;
    }

    @Override
    public void onOpen(SQLiteDatabase db) {
        Log.i(TAG, "onOpen db");
        if (createDb) {// The db in the application package
            // context is being created.
            // So copy the contents from the db
            // file packaged in the assets
            // folder:
            createDb = false;
            copyDatabaseFromAssets(db);

        }
        if (upgradeDb) {// The db in the application package
            // context is being upgraded from a lower to a higher version.
            upgradeDb = false;
            // Your db upgrade logic here:
        }
    }
}

Finally, to get a database connection, just call getReadableDatabase() or getWritableDatabase() on the SQLiteOpenHelper subclass and it will take care of creating a db, copying db contents from the specified file in the 'assets' folder, if the database does not exist.

In short, you can use the SQLiteOpenHelper subclass to access the db shipped in the assets folder just as you would use for a database that is initialized using SQL queries in the onCreate() method.

using (StreamWriter w = File.AppendText("myFile.txt"))
{
  w.WriteLine("hello");
}

The Declarative model for Jenkins Pipelines has a restricted subset of syntax that it allows in the stage blocks - see the syntax guide for more info. You can bypass that restriction by wrapping your steps in a script { ... } block, but as a result, you'll lose validation of syntax, parameters, etc within the script block.

/* eslint no-restricted-globals:0 */

is another alternate approach

U can use something like this....

  function (field,value) {

         var newItemOrder= value;
          // Make sure user hasnt already added this item
        angular.forEach(arr, function(item) {
            if (newItemOrder == item.value) {
                arr.splice(arr.pop(item));

            } });

        submitFields.push({"field":field,"value":value});
    };

After the query, run below to get the total row count

Check out python-nvd3. It is a python wrapper for nvd3. Looks cooler than d3.py and also has more chart options.

Well, here is one solution I ended up with, but I hope there's a more elegant one...

StringBuilder result = new StringBuilder();
for(int i=0; i<name.length(); i++) {
    char tmpChar = name.charAt( i );
    if (Character.isLetterOrDigit( tmpChar) || tmpChar == '_' ) {
        result.append( tmpChar );
    }
}

result ends up with the desired result...

As mentioned on the addMethod documentation:

Please note: While the temptation is great to add a regex method that checks it's parameter against the value, it is much cleaner to encapsulate those regular expressions inside their own method. If you need lots of slightly different expressions, try to extract a common parameter. A library of regular expressions: http://regexlib.com/DisplayPatterns.aspx

So yes, you have to add a method for each regular expression. The overhead is minimal, while it allows you to give the regex a name (not to be underestimated), a default message (handy) and the ability to reuse it a various places, without duplicating the regex itself over and over.

99% of our AWS setup is recyclable. So for me it doesn't really matter if I terminate an instance -- nothing is lost ever. E.g. my application is automatically deployed on an instance from SVN, our logs are written to a central syslog server.

The only benefit of instance storage that I see are cost-savings. Otherwise EBS-backed instances win. Eric mentioned all the advantages.

[2012-07-16] I would phrase this answer a lot different today.

I haven't had any good experience with EBS-backed instances in the past year or so. The last downtimes on AWS pretty much wrecked EBS as well.

I am guessing that a service like RDS uses some kind of EBS as well and that seems to work for the most part. On the instances we manage ourselves, we have got rid off EBS where possible.

Getting rid to an extend where we moved a database cluster back to iron (= real hardware). The only remaining piece in our infrastructure is a DB server where we stripe multiple EBS volumes into a software RAID and backup twice a day. Whatever would be lost in between backups, we can live with.

EBS is a somewhat flakey technology since it's essentially a network volume: a volume attached to your server from remote. I am not negating the work done with it – it is an amazing product since essentially unlimited persistent storage is just an API call away. But it's hardly fit for scenarios where I/O performance is key.

And in addition to how network storage behaves, all network is shared on EC2 instances. The smaller an instance (e.g. t1.micro, m1.small) the worse it gets because your network interfaces on the actual host system are shared among multiple VMs (= your EC2 instance) which run on top of it.

The larger instance you get, the better it gets of course. Better here means within reason.

When persistence is required, I would always advice people to use something like S3 to centralize between instances. S3 is a very stable service. Then automate your instance setup to a point where you can boot a new server and it gets ready by itself. Then there is no need to have network storage which lives longer than the instance.

So all in all, I see no benefit to EBS-backed instances what so ever. I rather add a minute to bootstrap, then run with a potential SPOF.

You appear to have a heredoc containing a single SQL*Plus command, though it doesn't look right as noted in the comments. You can either pass a value in the heredoc:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql BUILDING
exit;
EOF

or if BUILDING is $2 in your script:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql $2
exit;
EOF

If your file.sql had an exit at the end then it would be even simpler as you wouldn't need the heredoc:

sqlplus -S user/pass@localhost @/opt/D2RQ/file.sql $2

In your SQL you can then refer to the position parameters using substitution variables:

...
}',SEM_Models('&1'),NULL,
...

The &1 will be replaced with the first value passed to the SQL script, BUILDING; because that is a string it still needs to be enclosed in quotes. You might want to set verify off to stop if showing you the substitutions in the output.

You can pass multiple values, and refer to them sequentially just as you would positional parameters in a shell script - the first passed parameter is &1, the second is &2, etc. You can use substitution variables anywhere in the SQL script, so they can be used as column aliases with no problem - you just have to be careful adding an extra parameter that you either add it to the end of the list (which makes the numbering out of order in the script, potentially) or adjust everything to match:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count BUILDING
exit;
EOF

or:

sqlplus -S user/pass@localhost << EOF
@/opt/D2RQ/file.sql total_count $2
exit;
EOF

If total_count is being passed to your shell script then just use its positional parameter, $4 or whatever. And your SQL would then be:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&2'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

If you pass a lot of values you may find it clearer to use the positional parameters to define named parameters, so any ordering issues are all dealt with at the start of the script, where they are easier to maintain:

define MY_ALIAS = &1
define MY_MODEL = &2

SELECT COUNT(*) as &MY_ALIAS
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&MY_MODEL'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

From your separate question, maybe you just wanted:

SELECT COUNT(*) as &1
FROM TABLE(SEM_MATCH(
'{
        ?s rdf:type :ProcessSpec .
        ?s ?p ?o
}',SEM_Models('&1'),NULL,
SEM_ALIASES(SEM_ALIAS('','http://VISION/DataSource/SEMANTIC_CACHE#')),NULL));

... so the alias will be the same value you're querying on (the value in $2, or BUILDING in the original part of the answer). You can refer to a substitution variable as many times as you want.

That might not be easy to use if you're running it multiple times, as it will appear as a header above the count value in each bit of output. Maybe this would be more parsable later:

select '&1' as QUERIED_VALUE, COUNT(*) as TOTAL_COUNT

If you set pages 0 and set heading off, your repeated calls might appear in a neat list. You might also need to set tab off and possibly use rpad('&1', 20) or similar to make that column always the same width. Or get the results as CSV with:

select '&1' ||','|| COUNT(*)

Depends what you're using the results for...

In summary the answer is: set the font size of the form elements to at least 16px

function getFormData($form){
    var unindexed_array = $form.serializeArray();
    var indexed_array = {};

    $.map(unindexed_array, function(n, i){
        if(indexed_array[n['name']] == undefined){
            indexed_array[n['name']] = [n['value']];
        }else{
            indexed_array[n['name']].push(n['value']);
        }
    });

    return indexed_array;
}

You can set CustomFormat property to "dd-MM-yyyy" in design mode and use dateTimePicker1.Text property to fetch string in "dd/MM/yyyy" format irrespective of display format.

UPDATE:

This answer is outdated.

Like @jack-marchetti stated in his comment, and @devantoine with the link: https://developers.facebook.com/x/bugs/357750474364812/

Facebook has changed how the sharer.php works, as Ibrahim Faour replies to the bug filed with Facebook.

The sharer will no longer accept custom parameters and facebook will pull the information that is being displayed in the preview the same way that it would appear on facebook as a post, from the url OG meta tags.

Try this (via Javascript in this example):

'http://www.facebook.com/sharer.php?s=100&p[title]='+encodeURIComponent('this is a title') + '&p[summary]=' + encodeURIComponent('description here') + '&p[url]=' + encodeURIComponent('http://www.nufc.com') + '&p[images][0]=' + encodeURIComponent('http://www.somedomain.com/image.jpg')

I tried this quickly without the image part and the sharer.php window appears pre-populated, so it looks like a solution.

I found this via this SO article:

Want custom title / image / description in facebook share link from a flash app

and this link contained in an answer from Lelis718:

http://www.daddydesign.com/wordpress/how-to-create-a-custom-facebook-share-button-for-your-iframe-tab/

so all credit to Lelis718 for this answer.

[EDIT 3rd May 2013] - seems like the original URL i had here no longer works for me without also including "s=100" in the query string - no idea why but have updated accordingly

Most probably it has to do with caching on the device. Catching the exception and ignoring is not nice but my problem was fixed and it seems to work.

With Swift 5.2 and iOS 13.4, according to your needs, you can use one of the following examples to align your VStack with top leading constraints and a full size frame.

Note that the code snippets below all result in the same display, but do not guarantee the effective frame of the VStack nor the number of View elements that might appear while debugging the view hierarchy.

1. Using frame(minWidth:idealWidth:maxWidth:minHeight:idealHeight:maxHeight:alignment:) method

The simplest approach is to set the frame of your VStack with maximum width and height and also pass the required alignment in frame(minWidth:idealWidth:maxWidth:minHeight:idealHeight:maxHeight:alignment:):

struct ContentView: View {

    var body: some View {
        VStack(alignment: .leading) {
            Text("Title")
                .font(.title)
            Text("Content")
                .font(.body)
        }
        .frame(
            maxWidth: .infinity,
            maxHeight: .infinity,
            alignment: .topLeading
        )
        .background(Color.red)
    }

}

As an alternative, if setting maximum frame with specific alignment for your Views is a common pattern in your code base, you can create an extension method on View for it:

extension View {

    func fullSize(alignment: Alignment = .center) -> some View {
        self.frame(
            maxWidth: .infinity,
            maxHeight: .infinity,
            alignment: alignment
        )
    }

}

struct ContentView : View {

    var body: some View {
        VStack(alignment: .leading) {
            Text("Title")
                .font(.title)
            Text("Content")
                .font(.body)
        }
        .fullSize(alignment: .topLeading)
        .background(Color.red)
    }

}

2. Using Spacers to force alignment

You can embed your VStack inside a full size HStack and use trailing and bottom Spacers to force your VStack top leading alignment:

struct ContentView: View {

    var body: some View {
        HStack {
            VStack(alignment: .leading) {
                Text("Title")
                    .font(.title)
                Text("Content")
                    .font(.body)

                Spacer() // VStack bottom spacer
            }

            Spacer() // HStack trailing spacer
        }
        .frame(
            maxWidth: .infinity,
            maxHeight: .infinity
        )
        .background(Color.red)
    }

}

3. Using a ZStack and a full size background View

This example shows how to embed your VStack inside a ZStack that has a top leading alignment. Note how the Color view is used to set maximum width and height:

struct ContentView: View {

    var body: some View {
        ZStack(alignment: .topLeading) {
            Color.red
                .frame(maxWidth: .infinity, maxHeight: .infinity)

            VStack(alignment: .leading) {
                Text("Title")
                    .font(.title)
                Text("Content")
                    .font(.body)
            }
        }
    }

}

4. Using GeometryReader

GeometryReader has the following declaration:

A container view that defines its content as a function of its own size and coordinate space. [...] This view returns a flexible preferred size to its parent layout.

The code snippet below shows how to use GeometryReader to align your VStack with top leading constraints and a full size frame:

struct ContentView : View {

    var body: some View {
        GeometryReader { geometryProxy in
            VStack(alignment: .leading) {
                Text("Title")
                    .font(.title)
                Text("Content")
                    .font(.body)
            }
            .frame(
                width: geometryProxy.size.width,
                height: geometryProxy.size.height,
                alignment: .topLeading
            )
        }
        .background(Color.red)
    }

}

5. Using overlay(_:alignment:) method

If you want to align your VStack with top leading constraints on top of an existing full size View, you can use overlay(_:alignment:) method:

struct ContentView: View {

    var body: some View {
        Color.red
            .frame(
                maxWidth: .infinity,
                maxHeight: .infinity
            )
            .overlay(
                VStack(alignment: .leading) {
                    Text("Title")
                        .font(.title)
                    Text("Content")
                        .font(.body)
                },
                alignment: .topLeading
            )
    }

}

Display:

If you are animating a constraint by changing the constant instead of a view property none of the other methods work on iOS 8.

Example animation:

self.constraint.constant = 0;
[self.view updateConstraintsIfNeeded];
[self.view layoutIfNeeded];
[UIView animateWithDuration:1.0f
                      delay:0.0f
                    options:UIViewAnimationOptionCurveLinear
                 animations:^{
                     self.constraint.constant = 1.0f;
                     [self.view layoutIfNeeded];
                 } completion:^(BOOL finished) {

                 }];

Solution:

You need to remove the animations from the layers of any views being affected by the constraint change and their sublayers.

[self.constraintView.layer removeAllAnimations];
for (CALayer *l in self.constraintView.layer.sublayers)
{
    [l removeAllAnimations];
}

Here too I can reproduce this problem with scrapy and psycopg2 (both require C++ compiling), even though I have Microsoft Visual C++ Compiler for Python 2.7 installed.

It has to be noted that I use virtualenv. From your post I'm not sure whether you do the same.

Anyway I tried to skip the activation of the virtual environment. Then both scrapy and psycopg2 installed fine.

My hypothesis: there is a conflict between this 2014 C++ compiler for Python and virtualenv. I do not know why nor how to solve it (and I'd be glad if someone can suggest a workaround).

I thought that since the js file was already loaded, that I didn't need to load/enqueue it again in the separate add_ajax function.
But this must be necessary, or I did this and it's now working.

Hopefully will help someone else.

Here is the corrected code from the question:

// code to load jquery - working fine

// code to load javascript file - working fine

// ENABLE AJAX :
function add_ajax()
{
    wp_enqueue_script(
       'function',
       'http://host/blog/wp-content/themes/theme/js.js',
       array( 'jquery' ),
       '1.0',
       1
   );

   wp_localize_script(
      'function',
      'ajax_script',
      array( 'ajaxurl' => admin_url( 'admin-ajax.php' ) ) );
}

$dirName = get_stylesheet_directory();  // use this to get child theme dir
require_once ($dirName."/ajax.php");  

add_action("wp_ajax_nopriv_function1", "function1"); // function in ajax.php

add_action('template_redirect', 'add_ajax');  

It should be (-### is similar to -v):

echo | gcc -### -E - -march=native 

To show the "real" native flags for gcc.

You can make them appear more "clearly" with a command:

gcc -### -E - -march=native 2>&1 | sed -r '/cc1/!d;s/(")|(^.* - )//g'

and you can get rid of flags with -mno-* with:

gcc -### -E - -march=native 2>&1 | sed -r '/cc1/!d;s/(")|(^.* - )|( -mno-[^\ ]+)//g'

Maybe not as elegant but another possibility would be to write a formula to do the check and fill it in an adjacent column. You could then filter on that column.

The following looks in cell b14 and would return true for all the file types you mention. This assumes that the file extension is by itself in the column. If it's not it would be a little more complicated but you could still do it this way.

=OR(B14=".pdf",B14=".doc",B14=".docx",B14=".xls",B14=".xlsx",B14=".rtf",B14=".txt",B14=".csv",B14=".pps")

Like I said, not as elegant as the advanced filters but options are always good.

You can use a pseudo element to create the overlay.

.testclass {
  background-image: url("../img/img.jpg");
  position: relative;
}
.testclass:before {
  content: "";
  position: absolute;
  left: 0; right: 0;
  top: 0; bottom: 0;
  background: rgba(0,0,0,.5);
}

Modern answer (only relevant after Mercurial 2.1):

Use Phases and mark the revision(s) that you don't want to share as secret (private). That way when you push they won't get sent.

In TortoiseHG you can right click on a commit to change its phase.

Also: You can also use the extension "rebase" to move your local commits to the head of the shared repository after you pull.

I dont think there is any sdk support for sending mms in android. Look here Atleast I havent found yet. But a guy claimed to have it. Have a look at this post.

Send MMS from My application in android

This code works in IE as well as FF:

<div>
  <img style="width:auto; height:auto;vertical-align: middle;">
  <span>It does work on all browsers</span>
</div>

In your case, the first value to insert must be NULL, because it's AUTO_INCREMENT.

I had the same problem in Eclipse Oxygen with Tomcat 8 in ubuntu 16.04 LTS.

Solution: 1. Give permission to entire tomcat folder (chmod 777 -R /Tomcat) 2. Delete and re-add the server in eclipse 3. Restart eclipse 4. Start the tomcat server. It will work..........

This line means you instantiated a "List of ClientThread Objects".

private List<ClientThread> clients = new ArrayList<ClientThread>();

This line has two problems.

String hey = clients.get(clients.size());

1. This part of the line:

clients.get(clients.size());

ALWAYS throws IndexOutOfBoundsException because a collections size is always one bigger than its last elements index;

2. Compiler complains about incompatible types because you cant assign a ClientThread object to String object. Correct one should be like this.

ClientThread hey = clients.get(clients.size()-1);

Last but not least. If you know index of the object to remove just write

 clients.remove(23); //Lets say it is in 23. index

Don't write

   ClientThread hey = clients.get(23); 

   clients.remove(hey);

because you are forcing the list to search for the index that you already know. If you plan to do something with the removed object later. Write

   ClientThread hey = clients.remove(23); 

This way you can remove the object and get a reference to it at the same line.

Bonus: Never ever call your instance variable with name "hey". Find something meaningful.

And Here is your corrected and ready-to-run code:

public class ListExampleForDan {

    private List<ClientThread> clients = new ArrayList<ClientThread>();

    public static void main(String args[]) {

        clients.add(new ClientThread("First and Last Client Thread"));

        boolean success = removeLastElement(clients);

        if (success) {

            System.out.println("Last Element Removed.");

        } else {

            System.out.println("List Is Null/Empty, Operation Failed.");

        }

    }

    public static boolean removeLastElement(List clients) {

        if (clients == null || clients.isEmpty()) {

            return false;

        } else {

            clients.remove(clients.size() - 1);

            return true;

        }

    }
}

Enjoy!

Sometimes, you need to list the variables of an object and not for debugging purposes. The right way to do it is using get_object_vars($object). It returns an array that has all the class variables and their value. You can then loop through them in a foreach loop. If used within the object itself, simply do get_object_vars($this)

First off, when you create a "bare repository", you're not going to be doing any work with it (it doesn't contain a working copy, so the git branch command is not useful).

Now, the reason you wouldn't have a master branch even after doing a git init is that there are no commits: when you create your first commit, you will then have a master branch.

The problem is that pyarrow is saved by pip into dist-packages (in your case /usr/local/lib/python2.7/dist-packages). This path is skipped by Jupyter so pip won't help.

As a solution I suggest adding in the first block

import sys
sys.path.append('/usr/local/lib/python2.7/dist-packages')

or whatever is path or python version. In case of Python 3.5 this is

import sys
sys.path.append("/usr/local/lib/python3.5/dist-packages")

And for my fellow Europeans, try using this:

timestamp=$(date +%d-%m-%Y_%H-%M-%S)

will give a format of the format: "15-02-2020_19-21-58"

You call the variable and get the string representation like this

$timestamp

Use mcrypt_encrypt() and mcrypt_decrypt() with corresponding parameters. Really easy and straight forward, and you use a battle-tested encryption package.

EDIT

5 years and 4 months after this answer, the mcrypt extension is now in the process of deprecation and eventual removal from PHP.

Update! New & improved! Find plugin @ GitHub!

On another note, while that method is simple, I've created a jQuery plug (found at this jsFiddle, just copy and past code between comment lines) that makes changing the cursor on any element as simple as $("element").cursor("pointer").

But that's not all! Act now and you'll get the hand functions position & ishover for no extra charge! That's right, 2 very handy cursor functions ... FREE!

They work as simple as seen in the demo:

$("h3").cursor("isHover"); // if hovering over an h3 element, will return true, 
    // else false
// also handy as
$("h2, h3").cursor("isHover"); // unless your h3 is inside an h2, this will be 
    // false as it checks to see if cursor is hovered over both elements, not just the last!
//  And to make this deal even sweeter - use the following to get a jQuery object
//       of ALL elements the cursor is currently hovered over on demand!
$.cursor("isHover");

Also:

$.cursor("position"); // will return the current cursor position as { x: i, y: i }
    // at anytime you call it!

Supplies are limited, so Act Now!

Default Export (export default)

// MyClass.ts -- using default export
export default class MyClass { /* ... */ }

The main difference is that you can only have one default export per file and you import it like so:

import MyClass from "./MyClass";

You can give it any name you like. For example this works fine:

import MyClassAlias from "./MyClass";

Named Export (export)

// MyClass.ts -- using named exports
export class MyClass { /* ... */ }
export class MyOtherClass { /* ... */ }

When you use a named export, you can have multiple exports per file and you need to import the exports surrounded in braces:

import { MyClass } from "./MyClass";

Note: Adding the braces will fix the error you're describing in your question and the name specified in the braces needs to match the name of the export.

Or say your file exported multiple classes, then you could import both like so:

import { MyClass, MyOtherClass } from "./MyClass";
// use MyClass and MyOtherClass

Or you could give either of them a different name in this file:

import { MyClass, MyOtherClass as MyOtherClassAlias } from "./MyClass";
// use MyClass and MyOtherClassAlias

Or you could import everything that's exported by using * as:

import * as MyClasses from "./MyClass";
// use MyClasses.MyClass and MyClasses.MyOtherClass here

Which to use?

In ES6, default exports are concise because their use case is more common; however, when I am working on code internal to a project in TypeScript, I prefer to use named exports instead of default exports almost all the time because it works very well with code refactoring. For example, if you default export a class and rename that class, it will only rename the class in that file and not any of the other references in other files. With named exports it will rename the class and all the references to that class in all the other files.

It also plays very nicely with barrel files (files that use namespace exports—export *—to export other files). An example of this is shown in the "example" section of this answer.

Note that my opinion on using named exports even when there is only one export is contrary to the TypeScript Handbook—see the "Red Flags" section. I believe this recommendation only applies when you are creating an API for other people to use and the code is not internal to your project. When I'm designing an API for people to use, I'll use a default export so people can do import myLibraryDefaultExport from "my-library-name";. If you disagree with me about doing this, I would love to hear your reasoning.

That said, find what you prefer! You could use one, the other, or both at the same time.

Additional Points

A default export is actually a named export with the name default, so if the file has a default export then you can also import by doing:

import { default as MyClass } from "./MyClass";

And take note these other ways to import exist: 

import MyDefaultExportedClass, { Class1, Class2 } from "./SomeFile";
import MyDefaultExportedClass, * as Classes from "./SomeFile";
import "./SomeFile"; // runs SomeFile.js without importing any exports

WordPress include tags, categories and taxonomies in search results

This code is taken from http://atiblog.com/custom-search-results/

Some functions here are taken from twentynineteen theme.Because it is made on this theme.

This code example will help you to include tags, categories or any custom taxonomy in your search. And show the posts contaning these tags or categories.

You need to modify your search.php of your theme to do so.

<?php
$search=get_search_query();
$all_categories = get_terms( array('taxonomy' => 'category','hide_empty' => true) ); 
$all_tags = get_terms( array('taxonomy' => 'post_tag','hide_empty' => true) );
//if you have any custom taxonomy
$all_custom_taxonomy = get_terms( array('taxonomy' => 'your-taxonomy-slug','hide_empty' => true) );

$mcat=array();
$mtag=array();
$mcustom_taxonomy=array();

foreach($all_categories as $all){
$par=$all->name;
if (strpos($par, $search) !== false) {
array_push($mcat,$all->term_id);
}
}

foreach($all_tags as $all){
$par=$all->name;
if (strpos($par, $search) !== false) {
array_push($mtag,$all->term_id);
}
}

foreach($all_custom_taxonomy as $all){
$par=$all->name;
if (strpos($par, $search) !== false) {
array_push($mcustom_taxonomy,$all->term_id);
}
}

$matched_posts=array();
$args1= array( 'post_status' => 'publish','posts_per_page' => -1,'tax_query' =>array('relation' => 'OR',array('taxonomy' => 'category','field' => 'term_id','terms' =>$mcat),array('taxonomy' => 'post_tag','field' => 'term_id','terms' =>$mtag),array('taxonomy' => 'custom_taxonomy','field' => 'term_id','terms' =>$mcustom_taxonomy)));

$the_query = new WP_Query( $args1 );

while ( $the_query->have_posts() ) {
$the_query->the_post();
array_push($matched_posts,get_the_id());
//echo '<li>' . get_the_id() . '</li>';
}
wp_reset_postdata();
} else {

}

?>
<?php
// now we will do the normal wordpress search
$query2 = new WP_Query( array( 's' => $search,'posts_per_page' => -1 ) );

I have not tested your code but other things works

If you want to get the path info from request url

 var url_parts = url.parse(req.url);
 console.log(url_parts);
 console.log(url_parts.pathname);

1.If you are getting the URL parameters still not able to read the file just correct your file path in my example. If you place index.html in same directory as server code it would work...

2.if you have big folder structure that you want to host using node then I would advise you to use some framework like expressjs

If you want raw solution to file path

var http = require("http");
var url = require("url");

function start() {
function onRequest(request, response) {
    var pathname = url.parse(request.url).pathname;
    console.log("Request for " + pathname + " received.");
    response.writeHead(200, {"Content-Type": "text/plain"});
    response.write("Hello World");
    response.end();
}

http.createServer(onRequest).listen(8888);
console.log("Server has started.");
}

exports.start = start;

It might be worth mentioning that you can also create a .dockerignore file, to exclude the files that you don't want to copy:

https://docs.docker.com/engine/reference/builder/#dockerignore-file

Before the docker CLI sends the context to the docker daemon, it looks for a file named .dockerignore in the root directory of the context. If this file exists, the CLI modifies the context to exclude files and directories that match patterns in it. This helps to avoid unnecessarily sending large or sensitive files and directories to the daemon and potentially adding them to images using ADD or COPY.

You can use the following sql, UPDATE TABLE SET Column= replace(Column , ' ','')

using javascript:

here input element is used

<input type="text" id="fname" onkeyup="javascript:console.log(window.event.key)">

if you want to use multiline code use curly braces after javascript:

<input type="text" id="fname" onkeyup="javascript:{ console.log(window.event.key); alert('hello'); }">

You have a PivotTables collection on a the VB Worksheet object. So, a quick loop like this will work:

Sub RefreshPivotTables()
    Dim pivotTable As PivotTable
    For Each pivotTable In ActiveSheet.PivotTables
        pivotTable.RefreshTable
    Next
End Sub

Notes from the trenches:

1. Remember to unprotect any protected sheets before updating the PivotTable.
2. Save often.
3. I'll think of more and update in due course... :)

Good luck!

FWIW CloudFront supports streaming as well. Might be better than plain streaming from instances.

The most basic and easiest way to understand (I think):

import java.util.Scanner;

public class ToUpperCase {
    static Scanner kb = new Scanner(System.in);

    public static String capitalize(String str){
        /* Changes 1st letter of every word 
           in a string to upper case
         */
        String[] ss = str.split(" ");
        StringBuilder[] sb = new StringBuilder[ss.length];
        StringBuilder capped = new StringBuilder("");
        str = "";

        // Capitalise letters
        for (int i = 0; i < ss.length; i++){
            sb[i] = new StringBuilder(ss[i]); // Construct and assign
            str += Character.toUpperCase(ss[i].charAt(0)); // Only caps
            //======================================================//

            // Replace 1st letters with cap letters
            sb[i].setCharAt(0, str.charAt(i)); 
            capped.append(sb[i].toString() + " ");  // Formatting
        }
        return capped.toString();
    }

    public static void main(String[] args){
        System.out.println(capitalize(kb.nextLine()));
    }
}

You could do this

$("#input").blur(function(){
    if($(this).val() == ''){
        alert('empty'); 
    }
});

http://jsfiddle.net/jasongennaro/Y5P9k/1/

When the input has lost focus that is .blur(), then check the value of the #input.

If it is empty == '' then trigger the alert.

The difference between getHeight() and getMeasuredHeight() is that first method will return actual height of the View, the second one will return summary height of View's children. In ohter words, getHeight() returns view height, getMeasuredHeight() returns height which this view needs to show all it's elements

I think you can load it in a Word document object by using .NET office programmability support and Visual Studio tools for office.

And then use the document instance to re-save as an HTML document.

I am not sure how but I believe it is possible entirely in .NET without any 3rd party library.

The following code will fetch you desired results with duplicate items and their index values.

  for i in set(mylist):
    if mylist.count(i) > 1:
         print(i, mylist.index(i))

If the order of your integers is not required, and if there are only unique values

you can also use NSIndexSet or NSMutableIndexSet You will be able to easily add and remove integers, or check if your array contains an integer with

- (void)addIndex:(NSUInteger)index
- (void)removeIndex:(NSUInteger)index
- (BOOL)containsIndexes:(NSIndexSet *)indexSet

Check the documentation for more info.

In Python 3, they made the / operator do a floating-point division, and added the // operator to do integer division (i.e., quotient without remainder); whereas in Python 2, the / operator was simply integer division, unless one of the operands was already a floating point number.

In Python 2.X:

>>> 10/3
3
>>> # To get a floating point number from integer division:
>>> 10.0/3
3.3333333333333335
>>> float(10)/3
3.3333333333333335

In Python 3:

>>> 10/3
3.3333333333333335
>>> 10//3
3

For further reference, see PEP238.

this is the code for set method

1. Down the apache server by running below in putty cd $ADMIN_SCRIPTS_HOME ./adstpall.sh
2. Drop the Global temporary tables drop table t;

This will workout..

Here is how I would do it if working with a large number of "to remove" values that would take a long time to manually remove.

• -Put Original List in Column A -Put To Remove list in Column B -Select both columns, then "Conditional Formatting"
  -Select "Hightlight Cells Rules" --> "Duplicate Values"
  -The duplicates should be hightlighted in both columns
  -Then select Column A and then "Sort & Filter" ---> "Custom Sort"
  -In the dialog box that appears, select the middle option "Sort On" and pick "Cell Color"
  -Then select the next option "Sort Order" and choose "No Cell Color" "On bottom"
  -All the highlighted cells should be at the top of the list. -Select all the highlighted cells by scrolling down the list, then click delete.

You can do:

And the more general:

foo.kind_of?(String)

I think you should not consider any specific parser implementation. Java API for XML Processing lets you use any conforming parser implementation in a standard way. The code should be much more portable, and when you realise that a specific parser has grown too old, you can replace it with another without changing a line of your code (if you do it correctly).

Basically there are three ways of handling XML in a standard way:

• SAX This is the simplest API. You read the XML by defining a Handler class that receives the data inside elements/attributes when the XML gets processed in a serial way. It is faster and simpler if you only plan to read some attributes/elements and/or write some values back (your case).
• DOM This method creates an object tree which lets you modify/access it randomly so it is better for complex XML manipulation and handling.
• StAX This is in the middle of the path between SAX and DOM. You just write code to pull the data from the parser you are interested in when it is processed.

Forget about proprietary APIs such as JDOM or Apache ones (i.e. Apache Xerces XMLSerializer) because will tie you to a specific implementation that can evolve in time or lose backwards compatibility, which will make you change your code in the future when you want to upgrade to a new version of JDOM or whatever parser you use. If you stick to Java standard API (using factories and interfaces) your code will be much more modular and maintainable.

There is no need to say that all (I haven't checked all, but I'm almost sure) of the parsers proposed comply with a JAXP implementation so technically you can use all, no matter which.

If you are running Rails (its the default db in Rails) check the {RAILS_ROOT}/config/database.yml file and you will see something like:

database: db/development.sqlite3

This means that it will be in the {RAILS_ROOT}/db directory.

It's simple like 1,2,3:

1. use decimal module for fast correctly-rounded decimal floating point arithmetic:

   d=Decimal(10000000.0000009)

to achieve rounding:

   d.quantize(Decimal('0.01'))

will results with Decimal('10000000.00')

2. make above DRY:

    def round_decimal(number, exponent='0.01'):
        decimal_value = Decimal(number)
        return decimal_value.quantize(Decimal(exponent))

OR

    def round_decimal(number, decimal_places=2):
        decimal_value = Decimal(number)
        return decimal_value.quantize(Decimal(10) ** -decimal_places)

3. upvote this answer :)

PS: critique of others: formatting is not rounding.

The fetch mode only says that the association must be fetched. If you want to add restrictions on an associated entity, you must create an alias, or a subcriteria. I generally prefer using aliases, but YMMV:

Criteria c = session.createCriteria(Dokument.class, "dokument");
c.createAlias("dokument.role", "role"); // inner join by default
c.createAlias("role.contact", "contact");
c.add(Restrictions.eq("contact.lastName", "Test"));
return c.list();

This is of course well explained in the Hibernate reference manual, and the javadoc for Criteria even has examples. Read the documentation: it has plenty of useful information.

Received the same error , the problem was difference in the version of Android SDK which AVD was using and the version in AndroidManifest file. I could solve it by correcting the

android:minSdkVersion="16"

to match with AVD.

SaaS: Software as a Service Cloud application services or “Software as a Service” (SaaS) are probably the most popular form of cloud computing and are easy to use. SaaS uses the Web to deliver applications that are managed by a third-party vendor and whose interface is accessed on the clients’ side. Most SaaS applications can be run directly from a Web browser, without any downloads or installations required. SaaS eliminates the need to install and run applications on individual computers. With SaaS, it’s easy for enterprises to streamline their maintenance and support, because everything can be managed by vendors: applications, runtime, data, middleware, O/S, virtualization, servers, storage, and networking. Gmail is one famous example of an SaaS mail provider.

PaaS: Platform as a Service The most complex of the three, cloud platform services or “Platform as a Service” (PaaS) deliver computational resources through a platform. What developers gain with PaaS is a framework they can build upon to develop or customize applications. PaaS makes the development, testing, and deployment of applications quick, simple, and cost-effective, eliminating the need to buy the underlying layers of hardware and software. One comparison between SaaS vs. PaaS has to do with what aspects must be managed by users, rather than providers: With PaaS, vendors still manage runtime, middleware, O/S, virtualization, servers, storage, and networking, but users manage applications and data.

IaaS: Infrastructure as a Service Cloud infrastructure services, known as “Infrastructure as a Service” (IaaS), deliver computer infrastructure (such as a platform virtualization environment), storage, and networking. Instead of having to purchase software, servers, or network equipment, users can buy these as a fully outsourced service that is usually billed according to the amount of resources consumed. Basically, in exchange for a rental fee, a third party allows you to install a virtual server on their IT infrastructure. Compared to SaaS and PaaS, IaaS users are responsible for managing more: applications, data, runtime, middleware, and O/S. Vendors still manage virtualization, servers, hard drives, storage, and networking. What users gain with IaaS is infrastructure on top of which they can install any required platforms. Users are responsible for updating these if new versions are released.

Working with thicker strokes gets a bit messy, if you have the pleasure of sass try this mixin, not perfect and depending on stroke weight it generates a fair amount of css.

 @mixin stroke($width, $colour: #000000) {
      $shadow: 0 0 0 $colour; // doesn't do anything but I couldn't work out how to create a blank string and maintain commas
      @for $i from 0 through $width {
          $shadow: $shadow,
          -$i + px -$width + px 0 $colour,
          $i + px -$width + px 0 $colour,
          -$i + px $width + px 0 $colour,
          $i + px $width + px 0 $colour,
          -$width + px -$i + px 0 $colour,
          $width + px -$i + px 0 $colour,
          -$width + px $i + px 0 $colour,
          $width + px $i + px 0 $colour,
      }
      text-shadow: $shadow;
}

" once the info is added to the DB, should I delete the tuple? i mean i dont need the tuple anymore."

No.

Generally, there's no reason to delete anything. There are some special cases for deleting, but they're very, very rare.

Simply define a narrow scope (i.e., a function definition or a method function in a class) and the objects will be garbage collected at the end of the scope.

Don't worry about deleting anything.

[Note. I worked with a guy who -- in addition to trying to delete objects -- was always writing "reset" methods to clear them out. Like he was going to save them and reuse them. Also a silly conceit. Just ignore the objects you're no longer using. If you define your functions in small-enough blocks of code, you have nothing more to think about.]

Throwing exceptions in a constructor is not bad practice. In fact, it is the only reasonable way for a constructor to indicate that there is a problem; e.g. that the parameters are invalid.

I also think that throwing checked exceptions can be OK¹, assuming that the checked exception is 1) declared, 2) specific to the problem you are reporting, and 3) it is reasonable to expect the caller to deal with a checked exception for this².

However explicitly declaring or throwing java.lang.Exception is almost always bad practice.

You should pick an exception class that matches the exceptional condition that has occurred. If you throw Exception it is difficult for the caller to separate this exception from any number of other possible declared and undeclared exceptions. This makes error recovery difficult, and if the caller chooses to propagate the Exception, the problem just spreads.

^{1 - Some people may disagree, but IMO there is no substantive difference between this case and the case of throwing exceptions in methods. The standard checked vs unchecked advice applies equally to both cases.}

^{2 - For example, the existing FileInputStream constructors will throw FileNotFoundException if you try to open a file that does not exist. Assuming that it is reasonable for FileNotFoundException to be a checked exception3, then the constructor is the most appropriate place for that exception to be thrown. If we threw the FileNotFoundException the first time that (say) a read or write call was made, that is liable to make application logic more complicated.}

^{3 - Given that this is one of the motivating examples for checked exceptions, if you don't accept this you are basically saying that all exceptions should be unchecked. That is not practical ... if you are going to use Java.}

Someone suggested using assert for checking arguments. The problem with this is that checking of assert assertions can be turned on and off via a JVM command-line setting. Using assertions to check internal invariants is OK, but using them to implement argument checking that is specified in your javadoc is not a good idea ... because it means your method will only strictly implement the specification when assertion checking is enabled.

The second problem with assert is that if an assertion fails, then AssertionError will be thrown, and received wisdom is that it is a bad idea to attempt to catch Error and any of its subtypes.

The jQuery way:

$('#test').attr('id')

In your example:

$(document).ready(function() {_x000D_
  console.log($('#test').attr('id'));_x000D_
});

<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>_x000D_
<div id="test"></div>

Or through the DOM:

$('#test').get(0).id;

or even :

$('#test')[0].id;

and reason behind usage of $('#test').get(0) in JQuery or even $('#test')[0] is that $('#test') is a JQuery selector and returns an array() of results not a single element by its default functionality

an alternative for DOM selector in jquery is

$('#test').prop('id')

which is different from .attr() and $('#test').prop('foo') grabs the specified DOM foo property, while $('#test').attr('foo') grabs the specified HTML foo attribute and you can find more details about differences here.

You need to provide a candidate for autowire. That means that an instance of PasswordHint must be known to spring in a way that it can guess that it must reference it.

Please provide the class head of PasswordHint and/or the spring bean definition of that class for further assistance.

Try changing the name of

PasswordHintAction action;

to

PasswordHintAction passwordHintAction;

so that it matches the bean definition.

First try to understand how Entity Framework Connection string works then you will get idea of what is wrong.

1. You have two different models, Entity and ModEntity
2. This means you have two different contexts, each context has its own Storage Model, Conceptual Model and mapping between both.
3. You have simply combined strings, but how does Entity's context will know that it has to pickup entity.csdl and ModEntity will pickup modentity.csdl? Well someone could write some intelligent code but I dont think that is primary role of EF development team.
4. Also machine.config is bad idea.
5. If web apps are moved to different machine, or to shared hosting environment or for maintenance purpose it can lead to problems.
6. Everybody will be able to access it, you are making it insecure. If anyone can deploy a web app or any .NET app on server, they get full access to your connection string including your sensitive password information.

Another alternative is, you can create your own constructor for your context and pass your own connection string and you can write some if condition etc to load defaults from web.config

Better thing would be to do is, leave connection strings as it is, give your application pool an identity that will have access to your database server and do not include username and password inside connection string.

Using JDK 8 or above:

no external libraries used

You can create a new String object from the file content (Using classes from java.nio.file package):

public String readStringFromFile(String filePath) throws IOException {
    String fileContent = new String(Files.readAllBytes(Paths.get(filePath)));
    return fileContent;
}

I tried sudo apt install nginx-full. You will get all the required packages.

import urllib.parse
urllib.parse.urlencode({'spam': 1, 'eggs': 2, 'bacon': 0})

I've always used it on the command line and not as a library, but HTMLDOC gives me excellent results, and it handles at least some CSS (I couldn't easily see how much).

Here's a sample command line

htmldoc --webpage -t pdf --size letter --fontsize 10pt index.html > index.pdf

In Eclipse Kepler it is very easy to generate Web Service Client classes,You can achieve this by following steps .

RightClick on any Project->Create New Other ->Web Services->Web Service Client->Then paste the wsdl url(or location) in Service Definition->Next->Finish

You will see the generated classes are inside your src folder.

NOTE :Without eclipse also you can generate client classes from wsdl file by using wsimport command utility which ships with JDK.

refer this link Create Web service client using wsdl

Yes:

#include <iostream>
#include <functional>

struct null_ref_t {
   template <typename T>
   operator T&() {
      union TypeSafetyBreaker {
         T *ptr;

         // see https://stackoverflow.com/questions/38691282/use-of-union-with-reference
         std::reference_wrapper<T> ref; 
      };

      TypeSafetyBreaker ptr = {.ptr = nullptr};

      // unwrap the reference
      return ptr.ref.get();
   }
};

null_ref_t nullref;


int main() {
   int &a = nullref;

   // Segmentation fault
   a = 4;
   return 0;
}

We could use tidyr::extract()

x <- c("F.US.CLE.V13", "F.US.CA6.U13", "F.US.CA6.U13", "F.US.CA6.U13", 
  "F.US.CA6.U13", "F.US.CA6.U13", "F.US.CA6.U13", "F.US.CA6.U13", 
  "F.US.DL.U13", "F.US.DL.U13", "F.US.DL.U13", "F.US.DL.Z13", "F.US.DL.Z13"
)


library(tidyr)
extract(tibble(data=x),"data", regex = "^(.*?)\\.(.*?)\\.(.*?)\\.(.*?)$",into = LETTERS[1:4])
#> # A tibble: 13 x 4
#>    A     B     C     D    
#>    <chr> <chr> <chr> <chr>
#>  1 F     US    CLE   V13  
#>  2 F     US    CA6   U13  
#>  3 F     US    CA6   U13  
#>  4 F     US    CA6   U13  
#>  5 F     US    CA6   U13  
#>  6 F     US    CA6   U13  
#>  7 F     US    CA6   U13

#> 12 F     US    DL    Z13  
#> 13 F     US    DL    Z13

Another option is to use unglue::unglue_data()

# remotes::install_github("moodymudskipper/unglue")
library(unglue)
unglue_data(x,"{A}.{B}.{C}.{D}")
#>    A  B   C   D

Another way you can achieve the desired effect is to use this Material Search View library. It handles search history automatically and it's possible to provide search suggestions to the view as well.

Sample: (It's shown in Portuguese, but it also works in english and italian).

Setup

Before you can use this lib, you have to implement a class named MsvAuthority inside the br.com.mauker package on your app module, and it should have a public static String variable called CONTENT_AUTHORITY. Give it the value you want and don't forget to add the same name on your manifest file. The lib will use this file to set the Content Provider authority.

Example:

MsvAuthority.java

package br.com.mauker;

public class MsvAuthority {
    public static final String CONTENT_AUTHORITY = "br.com.mauker.materialsearchview.searchhistorydatabase";
}

AndroidManifest.xml

<?xml version="1.0" encoding="utf-8"?>
<manifest ...>

    <application ... >
        <provider
        android:name="br.com.mauker.materialsearchview.db.HistoryProvider"
        android:authorities="br.com.mauker.materialsearchview.searchhistorydatabase"
        android:exported="false"
        android:protectionLevel="signature"
        android:syncable="true"/>
    </application>

</manifest>

Usage

To use it, add the dependency:

compile 'br.com.mauker.materialsearchview:materialsearchview:1.2.0'

And then, on your Activity layout file, add the following:

<br.com.mauker.materialsearchview.MaterialSearchView
    android:id="@+id/search_view"
    android:layout_width="match_parent"
    android:layout_height="match_parent"/>

After that, you'll just need to get the MaterialSearchView reference by using getViewById(), and open it up or close it using MaterialSearchView#openSearch() and MaterialSearchView#closeSearch().

P.S.: It's possible to open and close the view not only from the Toolbar. You can use the openSearch() method from basically any Button, such as a Floating Action Button.

// Inside onCreate()
MaterialSearchView searchView = (MaterialSearchView) findViewById(R.id.search_view);
Button bt = (Button) findViewById(R.id.button);

bt.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            searchView.openSearch();
        }
    });

You can also close the view using the back button, doing the following:

@Override
public void onBackPressed() {
    if (searchView.isOpen()) {
        // Close the search on the back button press.
        searchView.closeSearch();
    } else {
        super.onBackPressed();
    }
}

For more information on how to use the lib, check the github page.

The solution i found was

const [files, setFiles] = useState([] as any);
